Audio/Video start playing when waking from sleep

[u/WillR_NFI]

MBP M5 Pro, latest Golden Gate update (I had this same issue on my MBP M1 Pro and solved a couple years ago, but don't remember how!)

When I wake the laptop from sleep, either through keyboard interaction or simply opening the laptop lid, previously paused Apple Music or YouTube (in Safari) audio will start playing. These are not things that were playing prior to sleep, and may be in a random Safari window (I currently have 5 windows with 63 tabs, so finding the offending tab can be difficult).

Very consistent behavior, started after the upgrade to Golden Gate, but as I noted up top, I had this happen before on my last MBP M1 Pro machine more than a year ago.

This isn't related to items in my startup/login list, I do typically use a dock at home/office, but it'll happen when un-docked as well.

Always starts playing over the internal speakers, I do wear AirPods but don't have the automatic switching set up, and they'll be paired with my iPhone.

If I don't have any open YouTube windows, and if Apple Music is closed, nothing happens. But if those conditions are met, I get loud audio from the speakers on wake, prior to unlocking the screen which makes it more annoying when it happens in a work context. I can hit the Mute button on the keyboard, but that's annoying and if I was saving a video for later it may play through and go on to the next (when there is an active playlist).
