Added the alsa-driver package, to be sure everyone gets the info.
The bug is also true for Nvidia HDA chips, you can look in the
duplicates for more info.

I can confirm this. On the same sound hardware (in a macbook), I cannot
hear any sound output from internal speakers or over a set of
headphones (perhaps due to lower-power speaker/headphones) and am
missing the same audio channels.

You received this bug notification because you are a
Confirming on my T60 with 82801G as well, including PCM going missing
intermittently. It works fine on -9, broken on -10. Unfortunately I am
reluctant to go back to -9 for normal use because of Very Annoying Bug
#129226 which is fixed in -10 !
One other detail: the PC speaker system bell noise is
I have the same I guess, but on different hardware (also uses the snd_hda_intel
driver though)
Using 2.6.22-9-generic it works straight away but with 2.6.22-10-generic mixers
are gone and the alsa device name changed a little. Feisty also had this
behavior by the way, I used snd_hda_intel
Confirming on my HTPC using ALC883 chipset (snd_hda_intel driver). I
lost many mixer channels. Most importantly the IEC958 (digital output
switch) which means I no longer have sound at all. Had to revert back to
2.6.22-9 which made it work again.
