I have a set of different youtube tabs open. The first five tabs all play sound perfectly normal. However, the sixth tab refuses to play anything. When I'm looking in another tab while letting that video play, it pops out like normal but marks the audio as muted and refuses to let me unmute the video. When I go back to the tab that should control it, the main video on youtube shows it's unmuted. I have already tried muting and unmuting that tab and I have already looked into the volume mixer settings. I thought maybe the audio got pulled because of it just being youtube, but no. I can get audio in other browsers. How do I fix this?
