audiosense-pi's Issues

RPi4 GPIO 26 - Reset

I have followed the instructions but GPIO pin 26 is set to an INPUT rather than a HIGH OUTPUT to bring the codec chip out of reset.

This means that nothing works!

Any ideas?

Audiosense-pi not loaded anymore after kernel update: 5.4.x to 5.10

it is working again after downgrading with:

sudo rpi-update 453e49bdd87325369b462b40e809d5f3187df21d

Error on 5.10:
tlv320aic32x4: probe of 1-0018 failed with error -121

RPI4, latest kernel, i2c10

Hi

I have a custom board using i2c10 as I need to use the serial port using i2c1 pins.

So I will have to recompile the overlay file but cannot find the original dtb file.

Can you help?

Thanks

Andy.

No audio on PH and Line output

Hi.
My hardware: RaspberryPi 4/4GB with latest Raspbian kernel 4.19.

I have two AudioSense-Pi that I have assembled myself.

I added all necessary entries to /boot/config.txt:
dtparam=i2c_arm=on
dtparam=i2s=on
dtparam=spi=on
dtoverlay=lirc-rpi
dtoverlay=audiosense-pi

My problem is that there is no audio signal on both headphone and line outputs.

Test i did:

1: ffmpeg -i Downloads/1kHz_44100Hz_16bit_30sec.wav -af "pan=stereo|c0=c0|c1=c0" -ar 48000 -f alsa hw:1,0

No audio output! I noticed that "time" increases every two to three seconds and "speed" drops from 0.99 downwards v. fast...
It's the same for both PCBs
Perhaps something is wrong on the PCB, but all the elements were new and I tried to assemble them very carefully!
I'm sure raspbian os recognizes AudioSense-Pi correctly. I carried out the test by giving an audio signal to the LineIn input and switched "Bypass" - HPL / R Output Mixer IN1L / R


I heard on the headphones what was on the line input... I2C is working...
OK.
For today I have to finish ...

Maybe someone has an idea where is the problem ....?
Or maybe someone already had such a problem ...?

Playback not working, getting input/output error

I have acquired a Raspberry Pi 3 Model B+ in order to test. Unfortunately, I am still having no success getting audiosense-pi to work. :-(

I am trying to use Linux raspberrypi 4.19.118-v7+ #1311

If I have headphones plugged in when I power it up, I hear a pop, and power light is on, so it is at least getting power.

Following settings are in config.txt:

dtparam=i2c_arm=on
dtparam=i2s=on
dtparam=spi=on

# Additional overlays and parameters are documented /boot/overlays/README
dtoverlay=audiosense-pi
# Enable audio (loads snd_bcm2835)
dtparam=audio=on

I see devices like so:

$ aplay -l

Subdevices: 1/1
Subdevice #0: subdevice #0

When attempting to play audio file, I hear nothing in headphones and get error eventually:

$ aplay -D hw:1 archer-theme-song-16bit-pcm.wav
Playing WAVE 'archer-theme-song-16bit-pcm.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
aplay: pcm_write:2053: write error: Input/output error

Any suggestions what issue could be or how to troubleshoot?
