ALSA broken after kernel upgrading to 2.6.36.2

After upgrading to 2.6.36.2, my laptop can no longer play and sounds. audacious gives me a warning message:

** WARNING **
Audacious has detected that your ALSA device has a broken timer.  A workaround
is being used to prevent CPU overload.  Please report this problem to your
Linux distributor or to the ALSA developers.

How can I fix this bug?

Re: ALSA broken after kernel upgrading to 2.6.36.2

I've only been seeing this since I started using custom kernels, such as kernel26-git which I am using now. Everything still plays fine, including all sound/music in Audacious; the only difference is that the "Visualization Analyzer Mode" with the colored bars sometimes lags badly in its rendering.

Your laptop wouldn't happen to be a...Toshiba, would it? /Toshiba L505D-S5983 here.

Do you have [most of] the following ALSA packages?

[skyalmian@alcyone ~]$ pacman -Qs alsa
alsa-firmware 1.0.23-1 [12.44 MB]
alsa-lib 1.0.23-2 [1.78 MB]
alsa-oss 1.0.17-1 [0.18 MB]
alsa-plugins 1.0.23-2 [0.23 MB]
alsa-utils 1.0.23-3 [1.92 MB]
lib32-alsa-lib 1.0.23-4 [0.83 MB]
lib32-alsa-plugins 1.0.23-6 [0.41 MB]

Check out this thread on the Audacious forums, it covers this exact issue. I didn't use the patch in there but I did swap out the stable Audacious packages for audacious-hg and audacious-plugins-hg in the AUR, which fixed the problem (unless I use Floating Point bit depth...).

What's just removed the warning for me (and apparently fixed the segfault on exit), is to use the File-Preferences menu and select "floating point" as the output bit depth.

Edit: This worked for about an hour, that's all sad  Very weird.
