Pyo warning: Portaudio input device HDA Intel HDMI: 0 (hw:0,3) has fewer channels (0) than requested (2).
Portaudio error in Pa_OpenStream: Invalid number of channels
Pyo error: From portaudio, Invalid number of channels
Portaudio error in Pa_CloseStream (pa_deinit): PortAudio not initialized
Portaudio error in Pa_Terminate (pa_deinit): PortAudio not initialized
Pyo error:
Server not booted.
Any ideas why this doesn't work? Audacity, pd-l2or, VLC and many other audio applications have no trouble communicating with my sound interfaces.
It seems like a problem in Portaudio (the backend that Pyo uses). This message in particular:
Pyo warning: Portaudio input device HDA Intel HDMI: 0 (hw:0,3) has fewer channels (0) than requested (2).
I've been getting that error sometimes and I can't seem to reproduce it consistently. My wild guess is that something else exclusively opened the input device, but I haven't looked hard enough at the Portaudio code base to confirm this.
Thanks for the answer Ali. Tried all sorts, making sure nothing else using audio, increasing priority of python, etc. No joy I'm afraid. And no idea why other audio applications (audacity, pd-l2ork etc.) do not have any such problems. Suspect something wonky about the python implementation vis á vis the low-level audio interface. As I said, all other applications involving audio work without a hitch.
