Thanks for your help. One other problem I notice with PA is that sometimes the sound sounds saturated, as if it was compressed up and then scaled back down. I have this problem after playing around with various volume settings (either pa- volume or alsamixer etc) The main problem here is the CPU usage, which is strange.
