Why is RDP microphone redirection not working?

• Local device and microphone connection type: The type of connection, like Bluetooth or USB, can affect microphone performance within an RDP session.
• RDP settings affecting microphones: Various RDP settings, including end-user device configurations and Group Policies, can influence microphone behavior during RDP sessions.
