I really don't get whats wrong with that driver.. Especially with the patch I 
gave to you applied... Its very similar to some alsa code I used in a little 
library I wrote for playing audio.. though the whole thing runs in a thread, 
so maybe thats why it maybe at max uses 3% cpu? (more if the DUMB plugin is 
in use ;) possibly LOTS more ;)) hmm.. seems I also skip setting a few of the 
hw parameters.. I wonder if that has anything to do with it.
