Player issues with Jukebox and Video

One of my players is having issues with the jukebox and webcam on our campaign. Out of 5 of us, she's the only one who can't hear any music that I play, and her webcam won't turn on and broadcast to us. Also, despite all of our video displays working for the rest of us, the only person whose video she can see is mine (I can't see her).  She has the master volume turned up, and her setting are on 'recieve/broadcast video'. We've also been using Roll20 for a few months now, and the problem never seems to fix itself. Can anyone help? 

There is a dedicated bug thread for the Roll20 WebRTC.  Please have your player go over there and post her: Operating System Browser and Version Description of the Issue WebRTC Debug Log (Click the "Download WebRTC Debug Log" button under the settings tab) (Be aware lhe log only exists in yours and your players browsers up until you or they refresh. So, you'll want to download the log right after you start having issues, but before anyone refreshes, to get the most useful information.)
