No audio from Firefox on any site
I started having an issue where I do not get any audio from Firefox. Everything else works fine. Firefox is not muted, it's not turned down in the mixer. I completely uninstalled using Revo Uninstaller to make sure ALL registry and directories were deleted. When I reinstalled it did not give me the "You've already installed" message, so I know this was a complete reinstall.... Still no audio at all.
Does the Firefox bar in the Volume Mixer show that Windows is receiving output from Firefox?
If so, the issue may be that Firefox is sending to a different output device than the one you're listening on. I frequently switch between laptop speakers (bleah) and Bluetooth headset and Firefox doesn't ever fail to follow. But some users have reported that Firefox may get stuck on a removed or disabled audio output device under some circumstances.
No, I don't think so. The green bar does not go up and down when there should be sound playing. Other apps do move the green display though, just not Firefox.
Anyone able to help or tell me where to go for help?
When audio is playing in a page, does Firefox show the little speaker icon on the tab? That icon also is a mute button; you can click and unclick it to mute and unmute.

If there's no speaker icon, hmm.
