mercurial OSS4: savemixer crashing?

Postby stimuli » Tue Nov 02, 2010 7:58 am

Title says it all. savemixer is crashing on my geode lx system every restart or soundoff.

Does 'ossmix' work, or does it crash too? If not, please paste that output here.

I also suggest to try and run savemixer manually (e.g. "savemixer -f ~/testfile" to save or "savemixer -L -f ~/testfile" to restore) and see if you reproduce this crash more easily. If so, try compiling the attached file (e.g. cc -I/usr/lib/oss/include/sys savemixer.c -o ~/savemixer), and use that savemixer. It has more verbose output, and will hopefully allow us to see where it crashes.

Still crashing. savemixer makes an empty/blank mixer.save

So the mixer controls are corrupted for some reason... It's a guess, but maybe this patch will be a start:
