Hello all,
I’ve been running into problems with PsychoPy 2022.2.4 (but also 2022.1.2) running under Kubuntu 20.04, in which pyo is reported as missing in the benchmark tool (output pasted below) despite being installed, as shown below:
pip install -U pyo
Requirement already up-to-date: pyo in ./.local/lib/python3.8/site-packages (1.0.4)
Instead, the backend fails to pygame, which has atrocious audio latency. When I try using PTB as the backend, it silently fails to use it as well, again defaulting to pygame and throwing this error the first time a sound is prepared to be called:

SyntaxError: Missing argument

Thus, I’ve no idea what I’m doing wrong or how to fix the audio issues so that I can use any backend besides pygame. I’ve read something about the 64 bit version not having pyo from 2019: Pyo in PsychoPy 3 -- missing? but I can’t find the specific thread that talks about 64 bit installations being a problem.
