[RubenGarcia]

Which demo project is affected:
https://github.com/godotengine/godot-demo-projects/tree/master/audio/mic_record

OS/device including version:
Huawei P30 lite, android Q

Issue description:
Demo plays music when requested, but recording audio and then playing it gives blank output.

I confirm the same demo works in windows, and that I added the "Record Audio" permission in the export.

This is likely an engine issue, not an issue specific to the demo. There's an open issue on the subject: godotengine/godot#86428
