I have a Thinkpad T410 where, after I installed Gentoo on it, everything "just 
worked (TM)". The sound is via the bog-standard Intel chips on the mobo and 
uses the hda_intel drivers. I didn't use the TP for a long time, just 
periodically updating Gentoo, but when I eventually did try to use it the 
sound was muted. This means I shut down the X server to remove complications 
from the desktop and from the console aplay doesn't produce any sound. 
Everything looks normal, driver modules loaded, alsamixer shows the usual 
output, channels all active. I booted to a windows partition and the sound 
works, so the hardware is OK. The very weird thing is if I put the TP to sleep 
with acpitool and wake it up again, the sound works for about 60 seconds and 
then dies. There is nothing in the message log at all when this happens. I 
upgraded the kernel but that didn't help.

This problem has been dragging on for some years and I am contemplating a 
complete re-install from scratch. But before I do that does anyone have any 
idea what I could try?

TIA
Robin
