Hmmm, sorry to hear that :( Can you figure out if your CPU supports SSE
and/or MMX ? cat /proc/cpuinfo will print the appropriate flags. It's
a celeron so it should.
Then you could try recompiling mythtv with:
CXXFLAGS="-Os -march=pentium4 -mmmx -msse"
and see wether that helps, you would add that to the settings.pro Also
try enabling ALSA by uncommenting it. Then you can try setting mythtv
sound output to "ALSA:default" just for comparison.
Also, is the box capable of using IO-APIC on UP ? That will distribute
IRQs, maybe something is sharing IRQs that doesn't like sharing. That
would require a kernel rebuild.
