Kernel Update 2.6.35-31-generic-pae kills sound

[Dr Denise M Noha]

On the recent update (weekend of 26th November) the new kernel 2.6.35-31-generic-pae kills sound on my dell laptop (Latitude E3620) as there is no linux-alsa-driver-modules-2.6.35-31-generic-pae for Maverick (10.10) in the repository.

Sound works if I revert to earlier kernel 2.6.35-30-generic-pae

Same issue with 2.6.35-31-generic on Maverick 10.10. Sound works fine if I boot to 2.6.35-30-generic.

$ lsmod | grep snd
$
$ aplay -l
aplay: device_list:235: no soundcards found...
$ lspci -nn | grep Audio
00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 03)

[NoOp (glgxg)]

Added note: sound also works with out issue (same system) when booting to 11.10 Oneiric 3.0.0-15-generic kernel.
So the issue seems to be directly related to 2.6.35-31-generic/2.6.35-31-generic-pae.

Sound is back with today's proposed kernel 2.6.35-32-generic:
