The bottom writing is from my application which see's this /dev/dsp is
being used by some other application. But I can't figure out what it is.
lsof -f -- /dev/dsp

You mught check to make sure your device isn't running full duplex...
that will make it busy as hell and eat up ALOT of cpu under alsa. Then
dink with your alsa settings ie: give it more priority, more cache, etc.
I used to get such messages, but I haven't seen one in awhile. Make sure
