For those that are having trouble with Audio playing through the headset to your PC speakers :
In Windows > Go to the Sound Settings > Advanced Sound Options
Then in this App volume and device preferences Go To the App Volume (for the applications)
and Find the Application you are playing thru on the Quest 2 - ie Chrome or whatever
and Lower the volume there to 0 My app shows an application icon and the name of my oculus device next to it.
I leave my volume at 5 so - if needed, I can barely hear it and know it is still working and then I can "adjust as needed"
