hey crew.
not sure what i have done wrong here. i upgraded my kernel from 2.6.23-rt1
to 2.6.24-rt1 and i have lost my sound. i'm using a rme multiface and an
onboard intel.
the .config file is virtually exactly the same and the modules load, the
hdspmixer loads and sound appears to play "into"(as i can see levels on
channels 1+2) when hdsp mixer using jack but not out alsa(no levels on
output of the mixer show at all), and alsa doesn't work at all. however, the
onboard intel work fine(alsa and jack) when the multiface is not plugged in.
i've probably missed something really simple but i can't put my finger on
it.
kernel 2.6.23-rt1

Well, it's not an obvious issue... But very simple to solve. It's a
bug in alsa 1.0.15 which is what's included in kernel 2.6.24.
Deactivate the kernel ALSA drivers, upgrade to ALSA 1.0.16, and use
the 1.0.16 drivers.

I had the same problem with the hdsp card with a MultiFace II
interface. The problem is that the way the matrix mixer is addressed
within the kernel driver has been changed and they got it slightly
wrong.
The problem appeared with the ALSA 1.0.15 which comes as part of kernel
2.6.24. It is fixed in ALSA 1.0.16 but there is also a patch for 1.0.15
here: http://mailman.alsa-project.org/pipermail/alsa-devel/2008-
January/005309…
The issue affects a vanilla 2.6.24 kernel and has nothing to do with
applying realtime patches.

Steve.

that patch seemed to work although i couldn't work out how to run the patch
but editing the hdsp.c file by hand work fine.
