It's baffling. I have a Dell computer with Windows 10. I can't get audio and video to work on any of 3 browsers (Firefox, E, and Chrome). Sometimes video works, then quits. Sometimes it doesn't work at all. sometimes I get video and no audio. Sometimes neither.
I checked my drivers and they all say they're working fine and don't need to be updated. Troubleshooter could find nothing. [*-)]

Thanks in advance.
