Lucas;
All in all I need some help here... is there a reason why chuck-alsa is not routing through pulse?
Probably :-) What is not clear to me though is that this is a ChucK issue. ChucK itself doesn't support PortAudio as such and I think few programs do. As I understand things PortAudio is meant to try to unify the rather baroque situation in Linux audio drivers and tries to catch and mix signals. ChucK doesn't send things directly to PortAudio (and we don't require it, probably partially because not everyone likes or uses PortAudio...) I don't know why PA fails to catch ChucK's signal or ChucK sends it in some uncatchable way. Likely this is the result of the used library (RTAudio). Of course as a answer that's no good to you (maybe others have better explanations?). Have you considered trying Jack for routing signals instead? Jack is meant for that; for routing and recording signals, and is quite good at it. You could also do it internally, by chucking the dac to WvOut and so having ChucK record all that ChucK does. That last option might be the most simple one. There is a example file that demonstrates this, have a look whether it suits your needs. Yours, Kas.
