Was Firefox still running when you disconnected HDMI connection? if so is sound fine after restarting Firefox?

Did you make sure sound for Firefox was not muted?

@James Firefox was still running when HDMI was disconnected. After: restart, reboot, reinstall it's still not working. Of course sound is not muted :) I've tried on several services as YouTube, Netflix etc. Video is working fine but not audio.

@Pkshadow Firefox is supporting HTML5 and all other stuff. Nothing helps.

As I said it was working for some time. Then I want to watch netflix on TV and it happened.
