Android guest mic does not transmit audio

<Current situation>

PC host is conducting a support session with an Android guest device.

The host mic audio is received by the Android device.

But the guest mic audio is not received by the PC host.

So the host can talk to the guest, but the guest can't talk to the host.

<Request>

Allow Android guest mic audio to be transmitted, so the host and guest can talk to each other during support session.
