Plex for Windows no audio

I recently got a new PC with Windows 11 and when I play any video on Plex I have no sound. I have tried EAC3 5.1 and AAC 2.0 audio files and neither have any sound whatsoever. They both play fine on the webapp.

I tried messing around with a bunch of the settings for the Plex player, but nothing seemed to help. I have a USB audio interface and a USB wireless headset and neither of them will play sound from Plex.

Not sure if relevant, but I downloaded the latest version of the Plex player today and I have the latest nvidia drivers. Any ideas why there is no sound?
