Check if bluetooth device supports LDAC/aptX HD/aptX/AAC and details

[ValdikSS]

Just FYI, the following codec IDs is by far the most complete one:

Mandatory:
0x00 - SBC

Optional:
0x01 - MPEG-1,2 (aka MP3)
0x02 - MPEG-2,4 (aka AAC)
0x04 - ATRAC

Vendor specific:
0xFF 0x004F 0x01   - aptX
0xFF 0x00D7 0x24   - aptX HD
0xFF 0x000A 0x02   - aptX Low Latency
0xFF 0x00D7 0x02   - aptX Low Latency
0xFF 0x000A 0x01   - FastStream
0xFF 0x012D 0xAA   - LDAC
0xFF 0x0075 0x0102 - Samsung HD
0xFF 0x0075 0x0103 - Samsung Scalable Codec
0xFF 0x053A 0x484C - Savitech LHDC

0xFF 0x000A 0x0104 - The CSR True Wireless Stereo v3 Codec ID for AAC
0xFF 0x000A 0x0105 - The CSR True Wireless Stereo v3 Codec ID for MP3
0xFF 0x000A 0x0106 - The CSR True Wireless Stereo v3 Codec ID for aptX

If you're using Ubuntu packages, make sure you installed pulseaudio-modules-bt, not pulseaudio-module-bluetooth, and rebooted.

[Lastique]

Another way to discover which codecs are supported by your Bluetooth device is this:

• Install bluez-hcidump.
• Make sure your device/headset is not connected.
• Run sudo hcidump avdtp.
• Connect your device.

In the initial output of hcidump there will be message exchange listing the sinks supported by the device as well as capabilities of the sinks, including codecs. Then there will be a "Set config" command saying which sink and codec is actually selected.

[EHfive]

@zylxpl
The options in Android dev mode show what codec are supported on your Android phone not your headphone

[EHfive]

@oxwivi
Seems your device also support a unknown codec, it might be aptX or one of other a2dp codecs.
You could build bluez from blueZ 5 or bluez git master to see more infomations.
In bluz 4, avinfo prints unknown in other codecs case(non SBC).

[EHfive]

1. Install package bluez-utils or bluez-tools which includes command avinfo

2. Get your bluetooth device address

3. Make sure that bluetooth device is disconnected

4. Run avinfo <bluetooth device address>

PS Idol animes are trash.

Excuse me??? Aji people ?

[zylxpl]

I installed bluez-tools, but there is no avinfo command. Ubuntu 18.04

[EHfive]

I installed bluez-tools, but there is no avinfo command. Ubuntu 18.04

That's why i wrote "aka bluez-utils"

1. Install package `bluez-tools` aka `bluez-utils` which include command `avinfo`

[zylxpl]

But there is no bluez-utils either. In fact, there is no bluez package with avinfo.

[EHfive]

But there is no bluez-utils either. In fact, there is no bluez package with avinfo.

Seems those files are removed by Ubuntu packgers.

You can build bluez from source, than you can find avinfo in tools/ subfolder after make

[zylxpl]

It a lot of effort just to check what codec are supported on my headphones. It is much quicker with dev options in android phone.

Anyway, thx for your great work. My headphones sounds much better on aptX vs SBC. Hope it will be merged soon.

[zylxpl]

Yeah, thats right, but it's posible to force use of specific codec, and when it won't work it simply mean that it is not supported by headphones.

[oxwivi]

Nah, the problems start with Debian land:

Now to see how to get bluez compiled.

Many thanks, amigo. Now then, should I fuck up my Debian with PPA or just compile it from source... None of the compiled files put into place by make install replaces existing bluez files from Debian packages right? And if it one day does gets mainlined in Debian (which I doubt, because patents) the make install files will get replaced and not conflict, yeah?

The modules only replace the original pulseaudio bt modules.

$ MODDIR=`pkg-config --variable=modlibexecdir libpulse`
$ find $MODDIR -regex ".*\(bluez5\|bluetooth\).*\.so"

/usr/lib/pulse-12.2/modules/module-bluez5-device.so
/usr/lib/pulse-12.2/modules/module-bluez5-discover.so

I can't give you advise because I don't familiar with using PPA in Debian.

@EHfive, I installed the package generated using @elvenfighter's script, and now I can't connect to my headset. Android phone can still connect. I just get the following on bluetoothctl:

[takatakatakatak]

@Lastique thank you for this, the hcidump was able to verify that my 1000xm2 are only connecting via SBC codec even after successful setup and install of EHfive pulseuadio modules.

Not sure where to go from here. Back to playing with /etc/pulse/default.pa to see if I can get one of the better codecs to load.

[takatakatakatak]

If you're using Ubuntu packages, make sure you installed pulseaudio-modules-bt, not pulseaudio-module-bluetooth, and rebooted.

That did it! I couldn't work out why it didn't work on first compile given that all of the dependencies were met, but having done as you suggested and run the make file again it has picked up aptX and aptX-HD ! Sounds fantastic. Been using it near 24 hours now and absolutely zero problems.

Still not sure why LDAC wasn't picked up given libldac was available and bluez command inserted in default.pa but to be honest I'm quite happy with the quality and battery life running aptxHD! This really does deserve to find its way into all of the repos, absolutely amazing job by EHfive and no reason it shouldn't be supported out of the box. Absolute game changer. I'm not going back to windows now!!

Thanks so much for your help.

Another way to discover which codecs are supported by your Bluetooth device is this:

Hi,

Where can I find the codecs supported by my headset?

[Lastique]

For some reason in your case there is no "All Capabilities" command and response, where the capabilities should be listed. But "Set config" says LDAC was chosen.

[raffaem]

Yes, LDAC it's what I had selected in blueman as my codec. So it is not showing all the capabilities but only the one I have selected.

But there is no bluez-utils either. In fact, there is no bluez package with avinfo.

Seems those files are removed by Ubuntu packgers.

You can build bluez from source, than you can find avinfo in tools/ subfolder after make

I opened a bug report asking Ubuntu maintainers to include a package that mirrors bluez/tools.

In the meantime, I compiled it from source:

git clone https://git.kernel.org/pub/scm/bluetooth/bluez.git/
cd bluez
autoreconf -i
./configure
make

This is the output for my WH-1000XM3
