In fact, this happened to me when I upgraded to alsa driver 1.0.18.
Going back to alsa-driver 1.01.7 solves the problem. I think your kernel
is using 1.0.18, and I doubt anyone is going to fix it.

The only option is reporting in the alsa-devel list , and maybe someone
there
can do anything about it.
