I would say not. Alsa should still allow you to use /dev/dsp* (my setup
certainly does). There is a kernel option under the Alsa setup called
"OSS PCM (digital audio) API". I think this is the one that provides
the /dev/dsp* devices for Alsa. The fact that you already have
/dev/dsp1 however implies that you probably already have this option
selected, so the problem must be elsewhere.
Have you tried changing the sampling rate in mythtv-setup? This might
help. Other than that, I'm not sure what to suggest - maybe someone
else will have some good ideas.
Robert.
