I’ve made some progress implementing a sounddevice backend for psychopy and it looks good. Let’s close this thread and move discussion to here:

Correct me if I’m wrong, but it seems like pygame for sound is becoming obsolete, and pyo brings nothing but headaches. If we were to make an in-house backend (maybe built with PyAudio?) to replace pyo or be an additional option, what are the requirements and priorities?
