Android audio limitations

[Shahnawaz04]

Device: Samsung Galaxy S24 FE (no 3.5mm jack)

Issue: USB-C dongle falsely reports a headset mic even when using a TRS (audio-only) headphone.

Result: Android routes mic input to non-existent external mic.

Symptom: Calls work (fallback), but BGMI fails because it blindly selects external mic → teammates hear silence.

Requirement: Need USB audio output while forcing internal microphone input.

Conclusion: This is a USB-C audio descriptor / Android routing limitation, not a faulty headset.
