I apologize as I’m sure this question has to have come up before, but I wasn’t able to find it via search.
After much troubleshooting of the common:
SC_PortAudioDriver: PortAudio failed at Pa_OpenStream with error: 'Unanticipated host error' could not initialize audio
I determined that I can get the scsynth.exe to run successfully only after installing the ASIO4ALL drivers and instructing the command to use them with the “-H” flag. How do I force the flag (and of course the “ASIO4ALL” argument") ?
Windows 10 ver. 1903 (64bit), Sonic-Pi 3.2.2
Edit: Realized I typed “scsever.exe” instead of “scsynth.exe”
