Problem:
When I build and run the app from Xcode, the microphone works fine, and I receive input. However, when running the app normally (outside of Xcode), I can’t seem to access the microphone. The debug logs indicate no microphone is detected.
Question:
Is there any additional configuration I need to do for the microphone to work in a normal (non-Xcode) run on Vision Pro? Or any common issues that could be causing the microphone access to fail in this scenario?
Thanks in advance for any insights!
Best,
Siddharth
