alsa-utils's Issues

Unable to use alsa utils with card who have id greather than 31

Hello Dear Alsa dev members,

I comme to you because i search to use multiple alsa loopback.
Unfortunatly by defaut all is blocked on a id maximum to 31 (32 sound cards).
I compile a kernel with the options CONFIG_SND_MAX_CARDS = 256.

I add this options in the /etc/modprobe.d/alsa-base.conf:

options snd-aloop \
index=10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32 \
id=lp0,lp1,lp2,lp3,lp4,lp5,lp6,lp7,lp8,lp9,lp10,lp11,lp12,lp13,lp14,lp15,lp16,lp17,lp18,lp19,lp20,lp21,lp22 \
enable=1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1 \
pcm_substreams=2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2 /

As you can see, i try to use ID greather than 31.

When i look to /proc/asound:

card10/  card17/  card24/  card31/  lp11/    lp18/    lp4/     oss/
card11/  card18/  card25/  card32/  lp12/    lp19/    lp5/     pcm

card13/  card20/  card27/  devices  lp14/    lp20/    lp7/     timers
card14/  card21/  card28/  lp0/     lp15/    lp21/    lp8/     version

card16/  card23/  card30/  lp10/    lp17/    lp3/     modules

I find my card with id 32.

I have try first to use speakertest and i get :

ALSA lib pcm_hw.c:1713:(_snd_pcm_hw_open) Invalid value for card
Erreur d'ouverture à la lecture: -22,Invalid argument

I have try to compile alsa-lib and alsa-utils with:

mkdir /usr/src/alsa
cd /usr/src/alsa

git clone git://git.alsa-project.org/alsa-lib.git alsa-lib
cd /usr/src/alsa/alsa-lib
./gitcompile --with-max-cards=256
make install

cd /usr/src/alsa

git clone git://git.alsa-project.org/alsa-utils.git alsa-utils
cd /usr/src/alsa/alsa-utils
./gitcompile --with-max-cards=256
make install

But i have alwais the same issue.

Can somme one help me please?

Add amixer --view, to filter playback, capture or all

alsamixer has

       -V, --view <mode>
              Select the starting view mode, either playback, capture or all.

Perhaps amixer could also have something similar,
e.g., so that

$ amixer --view capture

would only dump the capture related settings.
Currently one could say that

$ amixer --view all

is the default.

"aplay -D oss -l" still reads sound cards through ALSA, not OSS

I don't have any ALSA devices, only OSS devices.

When the OSS PCM is selected aplay still tries to read ALSA devices:

$ /usr/bin/aplay -D oss -l
aplay: device_list:272: no soundcards found...

$ /usr/bin/aplay -L
null
    Discard all samples (playback) or generate zero samples (capture)
oss
    Open Sound System

But /usr/bin/aplay x.wav plays it through the OSS card.

aplay should list OSS cards when -D is selected.
The ALSA interface should also list OSS cards when no ALSA cards are present but it doesn't.

[Question]: Mute all channels when starting X11

Hello, thank you for developing alsa-utils. I have a specific question pertaining to amixer.

Current behaviour

When starting X11 and i3 (my window manager), I would like to have all audio channels (speaker, headphones, etc.) muted. At the moment, I have the following command in my i3 configuration file:

amixer -q sset Master mute

And as expected, the Master channel is indeed muted after starting X11. However, when I connect or disconnect my headphones, the volume automatically reverts back to the volume that was saved during the last boot.

Expected behaviour

I would like all volume channels to stay muted. So for example after starting X11 and i3, I would like to see that both my speakers and headphones are muted, even when I plug/unplug the jack. Would you have any recommendations on how to do this?

I was considering manually muting both headphones and speakers with amixer and then re-using the alsa state file during boots. But I am unsure because this seems like a hack'ish solution.

System specifications

OS/Kernel: Arch Linux, 5.9.8-arch1-1, x86_64 GNU/Linux
alsa-utils: 1.2.4-2 (installed via pacman package manager)
wm: i3-gaps

Starting with 1.2.5 alsactl tries to initialize UCM even if it is not supported

Starting with alsa-utils 1.2.5 I observed the following warning on my machine when running alsactl restore 0, which I didn't receive prevously with alsa-utils 1.2.4:

$ alsactl -E 'HOME=/var/run/alsasound' -I -f /var/lib/alsa/asound.state restore 0
alsa-lib parser.c:2372:(load_toplevel_config) Unable to find the top-level configuration file '/usr/share/alsa/ucm2/ucm.conf'.
alsa-lib main.c:1405:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -2

The error message tells me that alsa-utils 1.2.5 now tries to initialize UCM by default which doesn't work since I don't have alsa-ucm-conf installed. After installing alsa-ucm-conf, the error message looks as follows:

$ alsactl -E 'HOME=/var/run/alsasound' -I -f /var/lib/alsa/asound.state restore 0
alsa-lib parser.c:242:(error_node) UCM is not supported for this HDA model (HDA Intel PCH at 0xf2530000 irq 35)
alsa-lib main.c:1405:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -6

From reading the alsactl man page, it seems to me that UCM should only be initialized by default if it is available. Since alsactl 1.2.4 did not attempt to initialize UCM on my machine, this seems to be a regression introduced in alsactl 1.2.5. If I disable UCM explicitly using alsactl -U, everything works as expected. Similarly, downgrading to alsactl 1.2.4 again also resolves the issue.

I am not familiar at all with alsa internals but if desired, I can check with git-bisect(1) which commit between v1.2.4..v1.2.5 introduced this regression.

Not building on Raspbian Buster

Make fails during linking because the object files are not created. If the compiler is run then the object file will build but the prefix added by Makefile seems to stop the copmilation from occuring. This is building v1.2.4. (Master refuses to build due to dependancy on later version of asoundlib.)

Translation for alsa-utils

I found the po folder but seems that there are not all the translations (I know there's a Spanish localization for example).

Is it enough to translate the po files and PR them? Or is there any other procedure?

Setting volume of headphones seems to apply to Speakers as well

When using amixer in the following way:

amixer -c 1 set Headphone 0% mute

I receive the following partial output from scontents:

Simple mixer control 'Headphone',0
Capabilities: pvolume pswitch
Playback channels: Front Left - Front Right
Limits: Playback 0 - 87
Mono:
Front Left: Playback 0 [0%] [-65.25dB] [off]
Front Right: Playback 0 [0%] [-65.25dB] [off]
Simple mixer control 'Speaker',0
Capabilities: pvolume pswitch
Playback channels: Front Left - Front Right
Limits: Playback 0 - 87
Mono:
Front Left: Playback 87 [100%] [0.00dB] [on]
Front Right: Playback 87 [100%] [0.00dB] [on]

which looks good. However, it appears that the volume is applied across both the Headphone control and Speaker control (or maybe even just the Master volume) as there is no output from the speakers after this even though it would appear they should have full volume and are not muted.

I am using the Ubuntu Groovy Gorilla update, so Linux kernel 5.11. The default installation uses pulseaudio, but I've switched things to pipewire and both cause the same issue presumably because both use ALSA. I started here because amixer seems to at least allow me to identify the problem. When I change the Volume for the Headphones to 100% using the following:

amixer -c 1 set Headphone 100% mute

the audio from the speakers is then fine. amixer appears to be showing the correct information (as per above) according to the audio, but the Headphone volume seems to be applying to the Speakers as well. Maybe someone can point me in a direction that I can find a solution to this, as it would appear that anytime headphones are plugged in, removing the headphones causes the same situation: no sound. I suspect amixer is working fine, but wherever the volume from amixer is applied, it does not appear to be set appropriately.

alsamixer: add "restore defaults" keystroke

There should be a way to "restore defaults" for all levels for this sound card.
And perhaps for each level individually too.

axfr/tests fail on hppa and sparc

There is a Gentoo bug about this test failures: https://bugs.gentoo.org/681652

The log on hppa says this:

The errors are similar on sparc. Does that depend on specific kernel features to be enabled? Also note that both architectures are big endian, which may or may not be related.

So the error seems to happen in libsamplerate.so

Switching the sync method to "SIMPLE" prevents the error from happening as alsaloop doesn't seem to make use of libsamplerate in this case.
The following modes run without failing but don't give the desired results:

pi@pi-snapserver:~ $ alsaloop -C hw:2,0 -P hw:3,0 -S 0  # SYNC_TYPE_NONE
pi@pi-snapserver:~ $ alsaloop -C hw:2,0 -P hw:3,0 -S 1  # SYNC_TYPE_SIMPLE
pi@pi-snapserver:~ $ alsaloop -C hw:2,0 -P hw:3,0 -S 2  # SYNC_TYPE_CAPTRATESHIFT
pi@pi-snapserver:~ $ alsaloop -C hw:2,0 -P hw:3,0 -S 3  # SYNC_TYPE_PLAYRATESHIFT

Only SYNC_TYPE_SAMPLERATE and SYNC_TYPE_AUTO (which selects SYNC_TYPE_SAMPLERATE) fail.

The modes SYNC_TYPE_NONE and SYNC_TYPE_SIMPLE don't crash for me, but they don't work and result in increasing latency until the fifos reset. (Which is another issue I guess)

Miss mapping to unmute the middle speakers for Creative X-Fi with 20K1 chipset cards in analog-output.conf

Hi there. I want to report some bug, that is present from long time and i think that can be fixed now.
With any configuration that uses center/subwoofer, that center gets muted by default for Creative X-Fi with 20K1 chipset cards, but if you have other card, that will not happen, because of missing configuration for Center/Subwoofer in analog-output.conf.
The missing thing in analog-output.conf is:

[Element Center/LFE]
switch = mute
volume = merge
override-map.1 = center,lfe

You can see my issue and fix there:
ChimeraOS/chimeraos#131

when aplaymidi exits the sustained notes are played forever.

Transfered from here:
OpenTTD/OpenTTD#7637

Expected Result

All notes are stoped before exit aplaymidi

Actual Result

Notes are sustained forever and I have to press the panic button on Qsynth

Steps to Reproduce

Open Qsynth with fluid-soundfonts
do this: aplaymidi --port 128:0 file.mid
do control+c to kill aplaymidi
Qsynth plays a note forever.

Possible fix

Capture SIGINT and send midi off messages before exit properly.

Feature request: volume parameter for aplay

I am currently in a situation where I'm trying to play a notification sound when a privacy friendly voice control system hears its wake word. Specifically, it's the Voco addon for the Mozilla WebThings Gateway, an open source smart home controller.

Up till now I used aplay for this. But I need/want to support a ReSpeaker USB microphone, and that device doesn't have a simple volume control. Unfortunately addons are not allowed to make changes to asound.conf (which could add softvol) or install something like Pulse audio to mitigate this situation, as those changes could affect other addons of the system.

My current solution has been to switch to a different available audio player, ffplay. It has a -volume parameter.

Having a -volume option actually works out quite nicely, as it allows sounds to be played at relative volume to each other. For example, I can play a music stream at 40% volume, while setting the audio feedback from the voice control to be louder so it can always be heard over the music.

The downside of ffplay is that it's slow to start up. It can take up to a second or two. Aplay's responses were pretty much instant, which I now realise was really valuable and important.

I'd prefer to switch back to aplay, but I'd need to somehow get aplay to output audio at a relative volume.

Is this possible somehow? And if not, would it be an idea to add this feature to aplay?

system stops working, depends on alsa-sink-ALC283

the system stops working, the disk is continues running... sometimes after 1-2 hours... the system comes back, full working after more than 8 hours...
what I was doing: it is always after looking some hours streaming movies with firefox

the alsa-info output is here:
http://alsa-project.org/db/?f=c02c95149f023eeb6db51e5c528d8890609f4ae8

the syslog shows this:

Typo in alsamixer(1) manpage

In the second paragraph of the "MIXER VIEWS" section, it says...

The currently selected item is drawn in red and/of emphasized.

...when it should say...

The currently selected item is drawn in red and/or emphasized.

[Feature request][alsactl] Allow -g/--ignore to be used with init command

It would be great if the -g/--ignore flag would have an effect on the init command as well, so that alsactl -g init does not print and exit with an error, if no sound cards have been found.

Since it can be checked for attached sound cards on Linux easily via /proc or sysfs, this is of minor importance, and probably there is a reason why it is as it is. In this case, probably the --help output could be extended by this info, which is currently only present in the man page. Reading the --help only, one (or at least me) would not guess that this flag is ignored by the init command.

aconnect doesn't connect by name if the device name starts with a number

Hello, i don't know if this is the right place, if it is not please tell me where to report the issue, but i had this problem:

i have this devices with aconnect -i :

client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '
client 14: 'Midi Through' [type=kernel]
0 'Midi Through Port-0'
client 16: 'FCA610' [type=kernel,card=0]
0 'FCA610 MIDI 1 '
client 20: '12Step' [type=kernel,card=1]
0 '12Step MIDI 1 '
1 '12Step MIDI 2 '

the last one, 12Step, only connects if i use the 20:0 notation, 12Step:0 doesn't works, my error message is in portuguese, i get this:

if i do

aconnect 12Step:0 "Pure Data":0

i get

Conexão falhou (Argumento inválido)

(connection failed, (invalid argument) )

if i try aconnect 20:0 "Pure Data":0 it works

if i try "12Step", or '12Step', they doesn't work either

i'm on ubuntu 20.04.2

amixer: "5%-" or "5%+" doesn't work with cset

I want to raise and low volume with keys. This works, this rise the volume 20%:

amixer set Master 20%+

And every time I run this command, it rise 20% more. But, when I want to use the card (because I need to do this):

amixer -c 0 cset name='Master Playback Volume' 20%+

It doesn't work. It seems that amixer takes only "20%" value and doesn't care about "+" or "-".

I have Debian Buster, Mate desktop.

alsactl do not save all the parameters

Hello everyone, my laptop need to mute the speaker for the full sound experience, when I configure alsamixer with all the levels and mute the speaker I execute "sudo alsactl store" but after rebooted all the levels and configuration are saved except for muting the speaker. I made some tests muting the master or the headphones and the executed "sudo alsactl store" and these are saved.

I have to manually in every boot mute the speaker, I 'm under arch linux, with others distros doesn't happen, can you give me a hand with this?, thank you

aplay change to use 16-bit samples by default is not backwards compatible and is not documented

The change introduced in 0c5948e breaks a lot of scripts and other programs I have which invoke aplay and expect the default sample format to be U8. While I think it's somewhat reasonable to make this change given that U8 is a rather low quality sample format, it's worth acknowledging that aplay has had this behavior for a very long time and many people probably don't expect it to change.

Given that the commit log seems to only talk about the case of arecord, I wonder if we could reach a compromise and keep the format as U8 for aplay and switch it for arecord, since users are unlikely to complain about poor sound quality when playing raw audio (surely they would take the time to get the sample format set up correctly before attempting to play raw audio).

Also, the man page has not been updated to reflect this change and still says that U8 is the default.

man: alsaloop man page error

There is a small typo in the alsaloop man page:

alsa-utils/alsaloop/alsaloop.1

Lines 76 to 86 in c9e9a79

    
           .TP 
        
           \fI\-c <channels>\fP | \fI\-\-channels=<channels>\fP 
        
           Channel count specification. Default value is 2. 
        
           .TP 
        
           \fI\-c <rate>\fP | \fI\-\-rate=<rate>\fP 
        
           Rate specification. Default value is 48000 (Hz). 
        
           .TP

"-c" is used for both "channels" and "rate". Thankfully, the source thinks otherwise and "-r" is used for "rate".

High CPU usage in mpd

I've ran into a strange bug in mpd where I get really high cpu usage. All the details are in the following two short threads.
MusicPlayerDaemon/MPD#391 (comment)
https://bbs.archlinux.org/viewtopic.php?id=241722 ( buttcake is me )
I can also solve the bug by adding

audio_output {
 type	"alsa"
 device	"hw:0,0"
}

to the mpd.conf

Volume is not restored after boot

I have archlinux updated system last sunday.

$ uname -a
Linux mypc 5.6.3-arch1-1 #1 SMP PREEMPT Wed, 08 Apr 2020 07:47:16 +0000 x86_64 GNU/Linux

I checked with alsa-restore.service and alsa-state.service. None of them work as expected.

My sound card is:

# lshw -C sound

Filtering/manipulating MIDI messages

Hi, I'm using aconnect to send MIDI data from one USB MIDI device to another.

I need to filter the messages, so that only one MIDI channel gets sent through, or ideally, send data that comes in on one channel from device A out to device B on a different MIDI channel.

Is there any way to do this just with the command line tools?

Can't aplay/arecord simultaneously inside and outside of linux container

Hi,
I run into a problem that can't aplay/arecord simultaneously inside and outside of linux container.

Steps to reproduce:

go into container's shell and exec a record command.

~ # lxc-attach -n Default -P /tmp/run/lxc
/ # arecord -d 60 /tmp/test.wav &
/ # Recording WAVE '/tmp/test.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono
/ # ps
PID USER TIME COMMAND
1 root 0:00 /sbin/init
3 root 0:00 /bin/sh
1519 root 0:00 arecord -d 60 /tmp/test.wav
1520 root 0:00 /bin/ash
1521 root 0:00 ps

exit and exec another record command outside of container

/ # exit
~ # arecord -d 60 /tmp/test.wav &
~ # ALSA lib pcm_dsnoop.c:641:(snd_pcm_dsnoop_open) unable to open slave
arecord: main:830: audio open error: Device or resource busy

[1]+ Done(1) arecord -d 60 /tmp/test.wav

playback has same problem as below

ALSA lib pcm_dmix.c:1089:(snd_pcm_dmix_open) unable to open slave
aplay: main:830: audio open error: Device or resource busy

Expect:
It should be allowed to play/record simultaneously inside and outside of linux container.

Here's my asound.conf:

~ # cat etc/asound.conf
pcm.asymed {
type asym
playback.pcm "dmix:0,0"
capture.pcm "dsnoop:0,0"
}

pcm.!default {
type plug
slave.pcm "asymed"
}

ctl.!default {
type hw
card 0
}

Is there anyone has experience of how to address it? Thank you.

1.1.9: test suite issue: axfer/test -> container-test loops forever

Looks like it is some issue with axfer/test -> container-test.

Bad vumeter data in aplay/arecord

In aplay.c the wrong count is passed to compute_max_peak(). Instead of "r * hwparams.channels" it should be "r * bits_per_frame / 8".

Also, the vumeter should really show an overall peak level percentage because the transitory 1/8 second one has very little value.

aplay: playing mono audio file alteres pulseaudio default Master left or right volume level

I am encountering an unexpected behaviour with pulse audio master volume in my application.

Description

If I set for example left channel to 100% and right channel 0%, and play mono audio file (i.e. audio file with 1 channel only), then I would expect to hear only the audio file on left channel.

The actual behaviour in the example of above is when playing the audio file, the Master volume right channel will be automatically adjusted to 50%. If play again it increases to 75% and so on.

This issue happens also with other R/L volume level, the case of above is just an example.

Important to note the case does not happen with stereo audio file where audio sounds on left only channel as we can expected.

Steps to repeat issue:

(a) Set mixer Lch to 100%, Rch to 0%

$ amixer -D default sset Master 65535,0
Simple mixer control 'Master',0
  Capabilities: pvolume pswitch pswitch-joined
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 65536
  Mono:
  Front Left: Playback 65535 [100%] [on]
  Front Right: Playback 0 [0%] [on]

(b) Play mono audio file

$ aplay -D default ringtone.wav
Playing WAVE 'ringtone.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono

Request

(1) Is it by design expected ?
(2) Is there a way to prevent this phenomenon (command option) ?

Out of bounds array reference aplay.c playbackv_go function

I was looking through the aplay source file and came across an out of bounds reference. The reason I was looking through the code is that I am using an i2s amp and there is this code:
/usr/bin/aplay -D default -t raw -r 44100 -c 2 -f S16_LE /dev/zero /dev/zero
The reason for it is:

We've added an extra helper systemd script that will play quiet audio when the I2S peripheral isn't in use. This removes popping when playback starts or stops. It uses a tiny amount of CPU time (on a Pi Zero, 5%, on a Pi 2 or 3 its negligible).

I thought there must be a way to just open the device and not have to use any CPU time actually playing nothing.
If anyone knows if this is possible then let me know. Thanks.

Any way back to the out of bounds.

In the function playbackv_go function of aplay.c there is a call to perror(names[channel]). However, instead of channel being equal to zero it is equal to channels which is 1 + the number of names being passed to the function.

while (count > 0 && !in_aborting) {
size_t c = 0;
size_t expected = count / channels;
if (expected > vsize)
expected = vsize;
do {
channel = 0; // Code to fix out of bound
r = safe_read(fds[0], bufs[0], expected);
if (r < 0) {
perror(names[channel]); // Out of bounds reference
prg_exit(EXIT_FAILURE);
}
for (channel = 1; channel < channels; ++channel) {
if (safe_read(fds[channel], bufs[channel], r) != r) {
perror(names[channel]);
prg_exit(EXIT_FAILURE);
}
}
if (r == 0)
break;
c += r;
} while (c < expected);

axfer: FTBFS of axfer with glibc-2.11 or before due to missing definition of POLLRDNORM

Reported by Jay Foster in alsa-devel list.
http://mailman.alsa-project.org/pipermail/alsa-devel/2019-January/144024.html

The v1.1.8 release brings FTBFS of axfer in his legacy toolchain (glibc v2.9)
for arm platform, due to missing definition POLLRDNORM and the others, used in
axfer/waiter-select.c. An option of -D_GNU_SOURCE for CFLAGS can suppress
the issue. With glibc v2.22, no issues.

During development period of axfer, this issue has never been got. More recent
version of glibc (v2.28) was used and the macro is available without any explicit
options.

Similar with #33

arecord/aplay man page should separate the options into three lists…

The arecord/aplay man page should perhaps separate the options into three lists

ones that affect recording,
ones that affect playing,
and ones that affect both.

Segmentation fault when using alsamixer to display a sof-soundwire card

The builtin soundcard on my XPS 9700 recently stopped working. I tried to use alsamixer to see what's going on, and it gives me a segmentation fault.

The program works segfaults as soon as I choose sof-soundwire as the sound card by pressing F6. But as long as I don't choose that, it works fine with other cards.

There's the backtrace:

Directions please...

Hello

I design and build audio equipment and would like to know where or how I would go about getting access to the sound states to control a GPIO for a raspberry Pi.

What I would like ideally is to control a GPIO state based upon actual non-zero data playback.
My desire is to use the GPIO to control a mute function to silence the interactive periods in DAC activity.
I know little to nothing about programming but imagine the function is intelligent enough to discern the difference between an open device and actual music playback.
Other methods keep open the device to keep from switching off and on, however, I am looking for a more professional and detailed method to create.

Any pointers helpful
thank you

arecord command stop when output file set /dev/null

How to reproduce it?

Input the below command, then record go on
arecord -r 96000 -c 4 -f S32_LE 1> /dev/null
Wait for some minutes, it depended on system memory size.
For example,system memory had 2G,
(2102410241024)/(96k4*32/8)=1400s

The results:

this command quit auto.

Expect:

This command should not be interrupted.

Typo in 00main file?

Hello,

Looking at the 00main file, I think I found a typo

Shouldn't GOTO="00_mainend" be GOTO="00main_end"

Edit: git blame says that the change is 12years old
