Hi Orcan,
I wrote a quick and dirty hack which compiles fine with portaudio19, but
i don't have portaudio installed

quality of this patch :) Please try it and complain if it works not..

these myself, but I wanted to leave it to the original author (Do you guys
accept patches?).
AFAIK, nobody has been actively maintaining the portaudio drivers. I'll
try to look in to this... but most of the devs (including me) have been
pretty busy this fall... so patches are most certainly welcome. Send
them to this list (as an attachment).
