The mic recording files are empty

Hello, I wander if you could help me. I created an elicited imitation task, in which participants hear sentences and repeat. Unfortunately, the data files supposed to include microphone recordings are completely empty. So far I have tried different output file type but it did not work. I am sure that PsychoPy accesses my microphone.

OS (e.g. MacOS Ventura 13.4.1):
PsychoPy version (v2022.2.5 Builder):
Standard Standalone? (y/n) Yes
**What are you trying to achieve? I am trying to have the recordings so that I can transcribe them.

**What did you try to make it work? So far I made sure that PsychoPy accesses my in-built microphone. I tried different outfile type, like waw, raw, I tried different types of audio libraries like ptb, pygame etc.

I am uploading my experiment here with a few sound files and spreadsheet in case it helps.

I would massively appreciate any advice!

Best wishes,
