Hallo,
I try to load the cx88-alsa with my HVR4000 but with the 2.6.27.x I got
a null-pointer assignment
- I had a look in the code but not see any serious.
I got 2 sound cards working in my system Xonar D2x and Intel HD (both
working)
here is the dump. Sorry I have not enough time for a closer look - but
ask me if more infos needed.
cheers
Chris

Hi all,
I had time to have a closer look to the cx88-alsa and its seems not the
problem here.
to got my intel HD sound-chip to work I complied the alsa-drivers-1.0.8a
and if I install the drivers and
load the cx88-alsa I got the OOPS. Without the alsa-drivers installed
everything working fine.
I will contact the alsa-team.
regards
Chris
