I can't seem to figure this out. The frontend is telling me something is
using /dev/dsp, but fuser /dev/dsp returns nothing. The Backend is seg
faulting with an unknown codec error in the log file. Any suggestions?
Xawtv works fine, and mythmusic works for me as well.
I have a AMD 2400, with 512 Ram
GForce2 Nvidia video card
I am using ALSA (snd-via82xx driver), I have tried 1.0.0, .98, and .96
versions. I have also tried native ALSA (which give me different errors)
