Firefox not playing sound over Docking station over HTML

I encountered a strange problem. My setup: Thunderbolt 3 docking station with plugged in HTML output to monitor. The monitor has jack output to my speakers. There is no problem playing sound from chrome or Spotify or any other application, but...

Opening anything in Firefox has no sound (Facebook videos, 9gag videos, Spotify web, YouTube). The most strange is that while I play a song in my Spotify app I launch a video it has sound. Then pausing my Spotify allows me to watch the video with sound, however after any page refresh (F5 or any navigation such as selecting another video) I get no sound at all again.

I am using up to date: Fedora 31 & Firefox 75.0 | Mozilla Firefox for Fedora - 1.0

Thanks for any help, with state like this I am pretty much forced to use another browser :(

Open Firefox and play content that should play sound, such as this Firefox video or a Flash video with sound. Click the volume icon in the Windows taskbar. Click Open Volume Mixer. The Volume Mixer window will appear. Make sure the sliders for Mozilla Firefox and Plugin Container for Firefox (for plugin content such as Adobe Flash) are not muted or at the bottom.

Thank You.


Thanks for replying, but I think you didn't read the description of the question.

I having the problem under Fedora not under Windows. Anyhow I have the sound enabled for Firefox, and as wrote the sound, in weird circumstances, is playing... So my problem still persists.
