I noticed this has been happening a lot lately. I usually have my speaker playing music from a youtube tab. If I open up a video on another tab, the youtube music tab’s sound will cut out. The current tab’s video will play with audio but I won’t hear audio from both tabs. The youtube tab’s video will still continue playing except with no audio. Firefox is browser I usually use if that helps.
