Hello,
I am new to Azure and recently set up an Azure Virtual Desktop (AVD) environment with three virtual machines. However, while the speaker works fine, the microphone from my local computer is not transmitting to the AVD session.
I have configured the RDP settings correctly to enable microphone redirection (please see the attached screenshot). Could you please help me resolve this issue?
Thank you!

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 RedirectionPlease 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.execlient (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.
