Please help -- I have tried every solution I could find on the Internet and nothing has worked.
I get no audio from YouTube or any Flash video, but regular audio (videos, games, anything outside the browser) works fine. The proper audio devices are selected in the Control Panel and all non-Flash audio seems to work fine.
I've tried uninstalling Flash, older versions of Flash, the newest version of Flash, uninstalling Firefox, the older versions of Firefox, the newest Firefox, Internet Explorer, Opera, and Safari. No Flash audio in anything.
I tried upgraded from Service Pack 2 to Service Pack 3 -- still no Flash audio. I tried uninstalling and reinstalling browser / Flash after SP3 -- still no Flash audio.
Flash audio always worked fine before, mysteriously stopped working months ago. No fixes in sight.
Please help. What could it be?
