[Bug 42361] Sound does not work on ThinkPad X60s

[Chris Howells]

Public bug reported:

Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
I am running Kubuntu dapper with the latest -21 kernel on a Lenovo
ThinkPad X60s.

Sound does not work on first boot on the X60s. This problem was also
reported in the forums here:

http://www.ubuntuforums.org/showthread.php?t=156146

Basically if I attempt to use any sound I get an error message such as:

chris at thinky:/usr/share/sounds$ aplay /usr/share/sounds/pop.wav
ALSA lib pcm_direct.c:783:(snd_pcm_direct_initialize_slave) snd_pcm_hw_params_any failed
ALSA lib pcm_dmix.c:831:(snd_pcm_dmix_open) unable to initialize slave
aplay: main:544: audio open error: Invalid argument

If I 'rmmod snd_hda_intel; modprobe snd_hda_intel' then sound starts
working.

On IRC crimsun walked me through blacklisting the snd_hda_intel and then
manually 'modprobe snd_hda_intel' after boot; sound still fails to work
until the module is rmmod'ed and modprobe'd.
