Jitsi Meet - Audio device not displaying in firefox


I’m currently experiencing an issue where one of my audio devices won’t display when using Jitsi Meet in firefox.

If I go into settings there is no drop down for audio devices as it’s only recognising my laptops built in mic and not my USB audio interface. When I have tried using chrome instead it recognises both devices and the drop down is available.

I’m fine to use chrome but firefox tends to run a lot smoother for me and I also thought it was worth reporting in case it is a bug.

Many thanks,
