I'm glad you reached a solution. You might also check the backports
kernel, which is currently linux-image-6.6.13+bpo-amd64
6.6.13-1~bpo12+1.

Re: Bluetooth sound problems Debian 12 GNOME

[Jan Krapivin]

Good news. Looks like I have solved the problem. As a last resort I have
bought another one wi-fi receiver, third one. It has *Realtek RTL8763BW*
chip

and *two antennas*. And finally all works fine. I have spent some hours,
using Bluetooth headphones, waiting for problems, but they hadn’t occur.
Small problem is that LTS Kernel 6.1 doesn’t support this device, so I have
used Liquorix kernel, which I have installed earlier. Though, I don’t need
this kernel, as it haven’t helped me with sound interrupts, which was my
hope at first. So… I bought more old Wi-fi receiver with *Realtek
RTL8761BUV* chip with antenna and it also works fine, and also works with
stable 6.1 kernel.

I am glad that situation found its resolution, though it is strange for me
that USB-dongle Bluetooth receiver (I don’t know the exact model) and
receiver on an internal wi-fi adapter (AX 210) have worked so poorly both.
Though I was in the distance not more than 2 meters from receiver.

Thanks for help

You may try to discriminate hardware/software issues when you comparing

admit that it is inconvenient since it may require at least a half of an 
hour to test each variant and regular working environment is unavailable.

Just a wild guess, unlikely it is true. Headphones might report battery 
charge level using a vendor protocol extension. 85 and 88 are decreasing 
in later messages.


Sound stream may be interrupted when headphones decide to balance 
battery discharge by switching device that communicates with laptop.


Perhaps messages related to input devices are different because it is 
Wayland session while I use KDE with X11 session, so in my case 
messages are "Watching system buttons" instead of "KEYBOARD...".


You may use --since and --until journalctl options to get system logs

It is strange. I can see in a Debian mailing list an answer

"Not sure if this is your case, I had the same problem but I upgraded from
11 to 12. The transition from pulse to pipewire was not smooth. So I nuked
anything *pulse* and *bluetooth* and reinstalled from scratch using the
Debian guide:

https://wiki.debian.org/PipeWire

Is this a brand new installation or an upgrade?"

But i can't see it in my mailbox


*ANSWER*


No, this is a clean new installation. And it looks like i have the
same problem on another laptop with Debian 12 XFCE (Pulseaudio).

But the problem is with *TWO* headsets, so i am in question whats
happening with Debian, because Linux Mint and Android works fine...

Re: Bluetooth sound problems Debian 12 GNOME

[Jan Krapivin]

Hello again. I have used *pactl subscribe *command and i think that in the
moment of sound interrupt there are the corresponding lines:

"Event 'remove' on sink-input #353
Event 'new' on sink-input #358
Event 'change' on sink-input #358"

As for journald i have a lot of such errors, but they don't influence the
audio quality:

"Mar 11 22:20:13 deb wireplumber[1357]: RFCOMM receive command but modem
not available: AT+XIAOMI=1,1,102,85,88,27,174"

There are some other mentions of the bluetooth/headphones, but they don't
meet the moment of sound issues. Full journald -f log is in an attachment.

I must say that i had an opportunity today to test a laptop with Debian 12
XFCE laptop with Pulseaudio and the problem is the same there. But, as i
said, on a laptop with Linux Mint XFCE everything is fine. That's strange.
What is the main difference between Linux Mint and Debian here..?

I also tried Liquorix 6.7 kernel but it didn't help.

Thanks.

The link above has an example

Another tool is

However at first I would check logs using journalctl. Maybe debug should

Either a software/hardware bug or some piece of software disables power

A2DP device tries to sleep after some period of time. At least SBC 
allows to decrease bitrate if connection is unreliable. I have read

Bluetooth sound problems Debian 12 GNOME

[Jan Krapivin]

Hello! I have a problem with sound quality when using bluetooth headphones
on Debian 12 GNOME.

Every ~20 minutes, sometimes less, sometimes more, sound interrupts for a
1-5 seconds with complete silence.

At first I thought that problem can be in the headphones, though it have
worked fine with Android phone and Linux Mint XFCE on a other laptop.

So I bought another headphones with support of different codecs: SBC, AAC,
and AptX.

And I have the same problem, but now I hear not only silence but also a
crackling, when sound interrupts.

I tried different codecs, including AAC (
https://forums.debian.net/viewtopic.php?p=777598#p777598). But the problem
prevails.

Yes, I must of course mention that there is absolutely no problems, when
using non-bluetooth devices like speakers, headphones etc.

The only workaround is to use HSP mSBC codec in Heandsfree mode, but the
sound is awful.

Though in mSBC there are no interruptions. I wonder why mSBC works fine and
SBC no..?

}”

pulse.cmd = [

{ cmd = "load-module" args = "module-always-sink" flags = [ ] }

{ cmd = "load-module" args = "module-switch-on-connect" }

]


Unfortunately I have no ideas what to try further as I am not a
power-user/techy.

I have tried to use PulseAudio, pipe-wire media session and not
Wireplumber, backported version of PipeWire, but all these attempts left me
with GDM/Gnome removed from the system! As Gnome now have
Pipewire/Wireplumber as dependency.

I want to try all options possible (if any) before I ditch Gnome in favour
of DE, that supports Pulseaudio.

P.S. I have tried two different bluetooth hardware modules, one on a Wi-fi
chip and one USB-stick, with no difference.

pulseaudio is provided by pipewire-pulse if you use pipewire. And you
should have wireplumber for your user. Check packages and systemd
services.

Are you sure you have no sound at all, and not just have really really
low volume?

I have a similar problem where I need to raise the volume in alsamixer
