[Bug 539948] [NEW] lost sound since update kernel to 2.6.31-20 generic

[Thoralf Freitag]

Public bug reported:

Since I'm using the current kernel 2.6.31-20 generic, the sound with my
IDT 92HD71B7X doesn't work. Booting kernel 2.6.31-19 everything is like
before.

With the kernel 2.6.31-20 there is no sound. Pressing the mute key OSD
shows sound on and the mute LED show's mute. Pressing mute key again,
OSD shows mute and the mute LED is switched of. In both cases, there is
no sound.

For support of mute LED and prevent heavy switch off noises, I have to
use the config item

options snd-hda-intel model=hp-dv4-1222nr enable_msi=1

in my alsa.conf.
