Gibberish audio and video input

Hello, Lately I'm having problems to connect with some of my players. In audio and video options i can't see the right devices only some kind of gibberish and I think this is the problem because when everything is working just fine i can see the audio con video devices correctly. Why is this? Thank you

Please carefully work through to the first three steps of our guide to Solving Technical Issues: Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome and Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable all add-ons/extensions. Step 3: Clear your cache If none of the above succeeds, please have your player thoroughly work through Step 4. (Don't forget the complete Console Log!) If you need additional information on how to capture a console log we have additional information here: Submitting a Console Log in Firefox Submitting a Console Log in Chrome Thank you!
