Hello.

It is actually a problem in a non-recent
alsa-lib. With alsa-lib from hg it works
fine, but breaks with 1.0.16.
The commit that introduced an incompatibility
is this one:
http://hg-mirror.alsa-project.org/alsa-kernel/diff/26b0243ab4fa/drivers/pcsp/pcsp_lib.c
I certainly was not considering the
maintenance problems it creates. :(
Perhaps should we revert this commit
for now, and reintroduce after the
next alsa-lib release?

FYI, the alsa-lib fix is this one:
http://hg-mirror.alsa-project.org/alsa-lib/diff/8a980469cd71/src/conf/cards/PC-Speaker.conf

The problem happened because the
softvol plugin doesn't support 8bit
formats. So the above config change
was needed.
