audio – MS Teams on Windows 10 – microphone not working when using RDP to laptop

I’m using remote desktop to go from my desktop to work laptop, but when I do this the microphone built into my work webcam disappears as an option and therefore no-one can hear me.

If I work directly on the laptop, MS Teams shows me this option which works fine:

Before Remote Desktop

But, when I remote from the desktop into the laptop, this screen changes and I don’t get any options in the microphone drop down:

During a Remote Desktop

The options I have set in the remote desktop for audio are:

Remote desktop audio settings

I have tried plugging the work webcam into my desktop and using remote audio for both playback and recording, and this does work but produces too much echo on the call for others (presumably as both the desktop and laptop are in the same room albeit on different desks). I also can’t use MS Teams on my desktop due to work policies, and I’m trying to avoid having to go between the desks so remote desktop would be ideal if I can get this microphone working.

Is there anything else I could try?
