Android TV - USB webcam microphone produces only digital noise (Philips TV + Papalook PA452)

Hello,

I would like to report what appears to be an Android TV audio input issue.

Hardware
TV: Philips 43PUS8507
OS: Android TV 11
Webcam: Papalook PA452 (USB UVC/UAC webcam with integrated microphone)
Jami version: Latest version from Google Play

Problem:

The webcam video works perfectly.

However, the microphone does not work correctly.

The remote participant only hears loud digital noise/static. No voice is transmitted.

Exactly the same hardware worked perfectly with Google Meet on the same TV before Google discontinued Android TV support.

Therefore:

the USB camera is working correctly,
the USB microphone is working correctly,
Android TV is capable of using this webcam.

Thank you very much in advance for your help.

Best regards, Jan
