Cannot Get Either Built-in Macbook Pro camera or Microphone/Speakers to work :(

Hello, Up until around a year ago, I was able to use Roll20 with my Macbook Pro no problem.  I was able to see and hear my party, and they were able to see me.  Then, the next session we played, there was no communication coming or going through the Chrome webpage of Roll20.  I had no changed any settings.  I tried to reconnect, set permissions to allow and all that stuff, but nothing seemed to work.  My Facetime camera works fine in other apps, but seems completely disabled through Roll20.  I also am not sending or receiving any party audio.  I have the latest version of Chrome installed, and still nothing.  Pleae help.

Hello Art D., I'm sorry to hear that you're having issues with the site. To rule out potential issues, please carefully work through Steps 1 through 8 of the Roll20 guide to  Audio Visual Troubleshooting : Step 1: Make sure you’re using the most recent version of either Chrome or Firefox Please check if these issues persist when using both Chrome  and  Firefox. Step 2: Give Roll20 permission to use your microphone and camera Step 3: Make sure Video and Voice are turned on inside Roll20 Step 4: Clear your Web Browser’s Cache Step 5: Make sure you have the right ports open Step 6: Check if your camera is working with WebRTC Step 7: Check that your camera is functioning Step 8: Do a bandwidth test If none of the above succeeds, please thoroughly work through  Step 9 : Step 9: Solving Technical Issues Step 9.2: Ensure that there are no extensions/addons interfering with Roll20 Please disable  all  add-ons/extensions. Step 9.4: Provide a bug report Please ensure that the Console Log is complete. If you have a macbook pro (or a macbook in general), try this: open a terminal and type "sudo killall VDCAssistant" to see if this solves the issue. Information can be found  here in an Apple forum post . Thank you!
