No sound on thinkpad t20 (cs46xx) in hoary (kernel 2.6.10)

[Ian Helgesen]

Sound does not work on thinkpad t20. System sounds default to internal speaker,
gnome apps give error "ALSA device "default" does not exist".

The problems appears to be that the /kernel/drivers/input/gameport/cs461x.ko
module is loading and is interfering with sound drivers. Removing this modules
eliminates the problem.

Steps to Reproduce:
1) Boot 2.6.10 kernel on t20.
2) Try to use any sound application.

Actual Results:
Error dialog reading "ALSA device "default" does not exist" appears.

Expected Results:
Sound plays

Thanks for the report. This module name will be added in the next
release.

It looks like the snd-cs46xx driver is able to drive the gameport itself, so I
think this module should be blacklisted by alsa-base

[Thomas Hood (jdthood)]

This was also reported in Debian bug report #294109. The name of the
cs461x module will be added to the blacklists in alsa-driver 1.0.8-5
which shouldn't be too long in coming.

Subject: alsa-base should blacklist cs461x kernel module for hotplug and discover

Package: alsa-base
Version: 1.0.8-4
Severity: normal

since alsa-base already blacklists cs46xx for both hotplug and
discover, it should also blacklist cs461x. Please add:

  cs461x

to /etc/hotplug/blacklist.d/alsa-base and add

  skip cs461x

to /etc/discover.d/alsa-base

Rationale:

i have a thinkpad T20.

alsa works fine, but since i switched to kernel 2.6.10, i've had to go
in and muck around with the module loading because the cs461x module
was getting loaded by hotplug (i'm not running discover). if cs461x
is loaded (in connection to the gameport module?), snd-cs46xx won't
have access to the hardware like it should.

According to this bug, this should be working now. Can you please confirm? =)

I installed hoary and

   cs461x

is indeed included in /etc/hotplug/blacklist.d/cs461x. So this bug report can
be closed.

[Jeff Bailey (jbailey)]

Great! Thanks for using Ubuntu.
