The extention works fine overall but i noticed that it realiably breaks audio output on http://meet.google.com. deactivating the plugin got it working again, activating the plugin breaks it. when the plugin is active, other people in the meeting can hear me, but i am not able to hear anybody else. audio in generall is working fine during this time, even youtube and even sound notifications in the meeting room as well as the video streams of the other people. only the sound is missing.
Should be fixed in 1.1 (which isn't on the store yet, but you can grab the extension code and try it out to confirm if you want)
