I ran my first roll20 session on Friday night, unfortunately after about a month of everything working fine whilst testing, the microphone stopped working about 15 minutes before the game started, and I haven't managed to get it working since then (I ran things by also being logged in via my laptop, and used the microphone on that, which wasn't ideal). I'm running Chrome on Linux (KDE/Ubuntu 13.10), using WebRTC. The camera works fine (it's a USB webcam which has phone/camera built in), and the microphone works fine in other applications (e.g. Google Hangouts) or on another machines, it just refuses to work within Roll20 on my desktop. I've tried wiping Chrome's cache (I've also restarted the machine etc). I've tried disabling/enabling video chat in Roll20. The same webcam works fine on another PC. As I said, it was working perfectly fine, until Friday night when it stopped working for no apparent reason. Any ideas on what I can try next to fix the problem? Thanks, Sam.
