Lost Sound

When I am watching a YouTube video and switch tabs, sometimes, on return to the YouTube tab, I have no sound. It is not muted. The system sound is fine. This does not always happen. I can switch tabs and still hear the sound. Then switch back and no sound. The video is not paused. I've tried pausing and playing the video, still no sound. Refreshing the tab doesn't help Where do I go to turn the sound back on? Win11, Firefox v144.02 64 bit.

What's showing in the mixer when this issue happens? see screenshot Also try different version of Firefox(Beta, Dev, or Nightly) and see if you have the same issue. Make sure to install in a different directory than your current install. https://www.mozilla.org/en-US/firefox/channel/desktop/
