Since about 5.17 kernel (2c95b92ecd92e784785b1db8cccc4f0f2bfa850c
upstream commit specifically), audio stops working after some time. The
real solution isn't known yet, but as a workaround disable problematic
feature (SG-buffer) for now. See linked issue and upstream discussion at
[1] for details.

Fixes QubesOS/qubes-issues#7465
