The AVD could not detect local microphone device

Hi Alvin IT,

I suggest you check the group policy setting on the remote PC.
Local Computer Policy->Computer Configuration->Administrative Templates->Windows Components->Remote Desktop Session Host->Device and Resource Redirection

Please ensure below two policies are enabled.

Allow audio and video playback redirection Allow audio recording redirection

And on the local pc, please enable below policy.

Local Computer Policy->Computer Configuration->Administrative Templates->Windows Components->Remote Desktop Connection Client->RemoteFX USB Device Redirection-> Allow RDP redirection of other supported RemoteFX USB devices from this computer.

You can refer to this document: https://learn.microsoft.com/en-us/azure/virtual-desktop/redirection-remote-desktop-protocol

If you are using the built-in mstsc.exe client (Remote Desktop Connection) to connect to RDP, and check its settings. Click on the Show Options button, navigate to the Local Resources tab, and click on the Settings button in the Remote audio section. Change from “Do not record” to “Record from this computer” in Remote audio recording.
