Audio doesn't work on Firefox

more options

I got a new computer recently, and the audio doesn't work on Firefox. Videos play normally, there's just no sound. I initially thought it was the computer, but when I tried on another browser, the audio worked fine. After searching for answers, I downloaded Adobe Flash and made sure it was listed in my Add-ons, but still no sound.

Help?!

For anyone else with this issue, the Volume Mixer on my computer had Firefox on mute. Here's directions! https://support.mozilla.org/en-US/kb/what-to-do-if-firefox-wont-play-any-sounds

I tried all the suggestions on this page: https://support.mozilla.org/en-US/questions/1200717, unchecking "Use hardware acceleration," making sure my drivers were updated, and Refreshed Firefox. Still no audio on any website on Firefox.

Does this also affect audio (mp3) files you play with the HTML5 media player ?

Are there media (audio) related messages in the Web console or Browser Console ?
