Remote controlling my pc from laptop and sending mic input?

I'm trying to call a friend on discord and play a game with them but can't due to the lack of a microphone. What I'm trying to do now is use teamviewer to remote control my main pc (there's NO way my laptop is going to be able to game at all) and use it's microphone.

However, I can't seem to get any response. I've set both playback and recording devices to their default on my laptop and pc (and the recording device on my pc IS getting input), but I can't hear anything on my main pc. Can anyone help me here?
