Yesterday my audio on Firefox worked, today it doesn't. I tried all the regular trouble shooting solutions. - My system volume is not 0 - My tabs aren't muted - My headphones are turned on and working fine (audio works everywhere but Firefox) - I uninstalled and reinstalled my Firefox - I uninstalled and reinstalled my headphone audio drivers - Audio also does not work in a private browser, so I know the issue it's related to extensions, cookies, etc. - I had Windows 11 do a quick diagnostic, so the issue isn't Windows 11 related

Usually when this issue occurs, it's as simple as switching from "default" to a specific speaker in volume mixer, but Firefox is not appearing in volume mixer like it did in the past, as shown in the screenshot below.

I don't know what else to do at this point. In previous documentation here, the solution for some people was to wait and it eventually fixed itself, but I'd rather not have audio for weeks to months on end, so has anyone found another solution by chance?

Wow it just works now, I don't even know what I did that made it worked. Here's what I did from making this post to now.

1. Uninstalled Firefox, restarted my PC, and THEN reinstalled. The audio still didn't work after this. 2. I went into Settings > Typed "Autoplay" in the textbox > My default was "Block Audio", so I switched it to a random one and switched back to "Block Audio" (from my understanding, "Block Audio" is the default, so I wouldn't change this unless you know what you're doing, unlike me). The audio still didn't work after this. 3. Complained to my mom that my audio wasn't working. The audio worked after this 😀 lmfao

My Firefox now appears in the audio mixer and I can hear through my headphones. I have no clue what the issue was.

Yeah, this is a common issue in Windows. Glad it's working. Mark this issue as resolved and have a nice day.
