I don't see why the solution to a sound problem should lie with an
xserver. Sound should work without X running at all. That's why
I wrote:
Once you've got those [alsamixer] settings, either quit with Escape,
or move to a different VC or window or xterm or whatever, and run
↑↑↑↑↑↑↑↑↑↑↑↑
$ speaker-test -D hw:0,0 -c 2
IOW you can perform the commands I gave after logging in at the
console, with no DMs, DEs, WMs or anything else.
But you may need a kernel more up-to-date than 5.10: there are
5.18 kernels in bullseye-backports, and these contain:
* HD audio interface patch for Cirrus Logic CS8409 HDA bridge chip
