Audio error but no audio in task

Hello,
Any help with this problem would be greatly appreciated! I downloaded PsychoPy on a new desktop and tried to run a task, but received the error below about audio libraries. However, my task does not have any need for an audio library or sound. Is there a way to get around this error so that my task will run? See error below:

2.0132 ERROR Failed to load any of the audioLibs: [‘ptb’]. Falling back to PsychToolbox (‘ptb’) backend for sound. Be sure to add ‘ptb’ to preferences to avoid seeing this message again.

Traceback (most recent call last):

Check whether the necessary audioLibs are installed.

Try changing the sound library from Experiment Settings / Audio

I tried changing the audio in experiment settings and tried all four audio settings (ptb, pyo, sounddevice, and pygame) and still get the same error.

My task does not use any audio (text and key responses only), so I’m not sure why it’s calling for audio and failing to run for that reason.

MacOS Sierra on a mac desktop with PsychoPy version v2024.2.4.

I’m having this exact same issue. I just installed on my lab Macs and can’t run any task of any kind because of this error. If anyone knows the fix, it would be really helpful right now. I didn’t have to install anything extra on my PC laptop to run things, so I have no idea what’s going wrong.
