I have a notebook with built in sound card:

A some point I noticed that volume became quite low; attempting to turn it up using volume control on notebook results in very audible noise that makes it impossible to actually use sound.
I am very casual sound user so I unfortunately cannot tell when exactly the problem appeared first; but I am pretty sure that in 2.6.14 I could normally watch video or listen CD without much strain.
I appreciate any pointers how to debug it further; if required I am ready to try to recompile older kernel (as time permits).
TIA
