[2.6.11] audio failing: ac97

[folkert@vanheusden.com (Folkert van Heusden)]

Hi,

I have a hp pavillion zv5231ea. Upto version 2.6.10 audio worked fine.
Since version 2.6.11 that stopped. Sound is silent or repeats the same
fragment over and over before doing the same with the next fragment.

During startup this is outputted:
...
atiixp: codec read timeout (reg 1c)
atiixp: codec read timeout (reg 0)

AC'97 2 does not respond - RESET
AC'97 2 access is not valid [0xffffffff], removing mixer.

(the timeouts appear a lot more by the way, I shortened things)
