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 

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-

The issue affects a vanilla 2.6.24 kernel and has nothing to do with 
applying realtime patches.
