I hope so, too. Please try the attached patch.


JFTR: You need at least ALSA-1.0.24 userland (or the corresponding
hdspm.h respectively) for the new driver (2.6.39 and above). Likewise,
if you intend to use hdspmixer, you need the yet unreleased 1.0.24.2
version of alsa-tools, so go for the git version:
