Hello, i’m using PsychoPy 3.2.2 and I want to record sound in my experiment.
The crush that I have is:
1.8660 WARNING We strongly recommend you activate the PTB sound engine in PsychoPy prefs as the preferred audio engine. Its timing is vastly superior. Your prefs are currently set to use [‘pygame’, ‘pyo’, ‘PTB’, ‘sounddevice’] (in that order).
13.7951 WARNING Starting Microphone but sound lib preference is set to be [‘pygame’, ‘pyo’, ‘PTB’, ‘sounddevice’]. Clashes might occur since ‘pyo’ is not preferred lib but is needed for Microphone
But when I change prefs to ‘PTB’, I have this mistake:
11.8420 WARNING Starting Microphone but sound lib preference is set to be [‘PTB’, ‘pygame’, ‘pyo’, ‘sounddevice’]. Clashes might occur since ‘pyo’ is not preferred lib but is needed for Microphone
If I’m not mistaken, the only package, which allows recording sound at the moment is pyo.
In your two attempts, which you show us above, you try to set first pygame, then ptb as your audio libs, which don’t allow audio recording for now (if I’m not mistaken).
Does your experiment still crash if you set your sound lib preference to pyo?
N.b.: What you show us above are warnings, not errors! Does your experiment actually crash, or are you just worried by the warnings and from what you can tell everything is running fine (except for the warnings).

Should I set something else except preferences and the microphone in builder? (I am very new to PsychoPy)
On Mac I have the problem:

Hi, marcolovoi, Have you solved the ptb/pyo issue in PsychoPy? It constantly reminds me of setting either ptb or pyo as preferred, but when I set either as preferred, warnings will appear that the other one should be preferred.
