Kernel version 2.6.32.9 (probably any 2.6), ALSA 1.0.22.1.

This patch is available here, too:
http://ristosu.wippiespace.com/pub/alsa-tumbler-1.0.22.1-p16d.diff

It has no effect, unless one changes '#undef DEBUG' to '#define DEBUG'
in the beginning of the file (and possibly in tumbler.patch, too).
