[Debian-eeepc-devel] no sound on 1101ha after lenny -> squeeze upgrade

after getting native screen resolution working, i noticed that there is
no sound after lenny -> squeeze upgrade.  i can give 'aplay file.wav'
command and it takes normal time to execute (to play the file), produces
no errors, but there is no sound.  i have checked with alsamixer and all
levels are ok and nothing is muted.

below is info about my sound configuration.  i don't remember changing
anything, i.e., everything should be "out of the box".  sound worked ok
in lenny.  any ideas?
