Bug Description

Binary package hint: linux-ubuntu-modules-2.6.22-14-generic

I'm running Gutsy on a Lenovo T61. Sound usually works fine, even after suspend & resume. However, once in a blue moon I lose sound after a suspend & resume. Applications think they're playing, but no sound comes out from the speakers. Alsamixer shows all channels unmuted and volume nonzero. A reboot fixes things.

dmesg shows a suspicious message in the middle of the resume process:

    hda_intel: azx_get_response timeout, switching to single_cmd mode...

Removing and reloading the snd-hda-intel module fixes things too, and also adds this to dmesg:

    hda_intel: azx_get_response timeout, switching to polling mode...

FWIW during boot, hda_intel prints nothing to dmesg.

I have the same behaviour on a T60, but in my case not even a cold boot fixes things. Is there anything else I could try?
