For the oldstable distribution (sarge), this problem has been fixed in
version 1.0.8-7sarge1. The prebuilt modules provided by
alsa-modules-i386 have been rebuilt to take advantage of this update,
and are available in version 1.0.8+2sarge2.

For the stable distribution (etch), this problem has been fixed in
version 1.0.13-5etch1. This issue was already fixed for the version of
ALSA provided by linux-2.6 in DSA 1479."
