[Pkg-utopia-maintainers] Bug#1082772: Additional ways to avoid the sound crackling issue

[Tyler Riddle]

I'm still trying to figure out what is going on with the audio crackling.
Here's what I've identified that I can do so far to avoid the crackling
problem:

1) Use the linux-image-6.1.0-17-amd64 or earlier kernel package along with
pipewire
2) Use the linux-image-6.1.0-18-amd64 or later kernel package with pipewire
stopped and pointing audio clients at the ALSA devices natively or use
jackd2 1.9.21~dfsg-3 or pulseaudio 16.1+dfsg1-2+b1

I still don't understand why the kernel versions matter but I have been
able to identify that it is not a problem specifically with the Debian
built kernels. I have run experiments where I build a kernel from the
official 6.1 releases from kernel.org using the kernel config file from
linux-image-6.1.0-17-amd64 and accepting all defaults when running make
oldconfig.

Doing some bisecting I've found the audio crackling does not happen with
6.1.52, which is what linux-image-6.1.0-12-amd64 is built from, and does
happen with 6.1.75, which sits between linux-image-6.1.0-17-amd64
and linux-image-6.1.0-18-amd64.

At this moment my machine is running 6.1.112 which I built myself and
configured as mentioned earlier. The audio crackling was very bad with
pipewire 1.2.4-1~bpo12+1.

After 3 days of validation I have had no problems at all using 6.1.112 with
pulseaudio 16.1+dfsg1-2+b1.
