I am using Csound version 5.09 beta (float samples) Sep 13 2008 on a fresh machine and portaudio is working fine? In the float version anyhow. Here is a snapshot of teh output:

   4: EDIROL UA-25
   5: SigmaTel C-Major Audio
   6: EDIROL UA-25
PortAudio: selected output device 'EDIROL UA-25'

I can only get it to work in realtime with MME audio out (-+rtaudio=mme),
portaudio does not work (-+rtaudio=pa).
