Cannot redirect microphone through to 2019 RDS server

Question

We're trying to pass through microphone input from a client to a 2019 server with the remote desktop session role installed.

Clients can connect to windows 10 computers and microphone works okay.

The server in question has "audio recording" enabled on the RDS host.
The group policy (allow audio recording redirection) is set to enable.
The fDisableAudioCapture is set to 0 (This is the group policy setting key anyway).
The audio service is started in the services list.

The audio devices do show up in the client session.

We are setting the client to send audio, and confirmed this works with a windows 10 as the host.

Also installed a fresh 2019 server with RDS role to test with no luck either.

Answer 1

Remote Desktop Services is currently not supported in the Q&A forums, the supported products are listed over here https://learn.microsoft.com/en-us/answers/products (more to be added later on).

You can ask the experts in the dedicated Remote Desktop Services forum over here:
