I've now successfully build and booted a 5.10.16 kernel 'pristine' and with 
the above mentioned patches.
In the 'pristine' variant, I had the same bad/horrible quality as I 
experienced with Debian's 5.10 kernels.
The 'patched' variant seems to be a tad better, but didn't completely solve 
the audio problem. There's still some noise intermixed with the music and 
other artifacts, but I'm inclined to think it's not as horrible as before.

I'll do some more hearing tests tomorrow when I'm fresh again, but figured I'd 
share these preliminary results already.

Cheers,
  Diederik
