Hey, has anyone been seeing strange behavior from this
combination?
kernel 2.6.31.x rt20 + alsa 1.0.22 userland
RME card (pcmcia card + multiface)
hdspmixer is not doing the right thing (does not initialize the card in
a way in which playback works), it does not see the hwdep interface (or
something like that) and disables metering, alsamixer even segfaults
when I reach the end of the controls listed. Plain weird. Smells like
something changed deep in the kernel that makes alsa-lib very unhappy.
Alsa-tools rebuilt from source does not make a difference.
Weirdness goes away when I boot into 2.6.29.6 rt23...
Is there anything in alsa-* that depends on which _kernel_ is available
at compile time?

Hi,
I'm actually using a similar combination on my gentoo without problem
(PCI card).
AFAIK the only difference between 2.6.30 and 2.6.31 for the hdsp is a
patch I made allowing the firmware to be built inside the kernel. It
should not have this kind of side-effect.
I'll check on my notebook with the PCMCIA card as soon as I can.
If you're using a custom built kernel you might want to try with the
firmware built-in.
