Note: this is not a request for troubleshooting help.
For the past few years my 10ish year old “smart” TV will maybe once a week or so completely lose the ability to play sound in the Youtube app, and only in the Youtube app. Sound works just fine everywhere else. Bizarrely this is always triggered by an ad and never a video. Restarting the app doesn’t fix it, and neither does clearing the cache. Fortunately doing a full restart of the TV fixes it, it’s just irritating to have to restart because an ad somehow broke the sound.
My computer turns itself on when I walk through a certain spot nearby it.
"Ah, you must have your mouse or some other peripheral set to activate it and the vibrations from walking-" Nope, I know how to disable wakeup from peripherals. "Well, then the vibrations from walking must be disturbing a loose component inside-" Nope, problem existed through a near-complete teardown and OS reinstall. Also, putting the PC on vibration isolating foam did not help.
At this point, I'm down to two conclusions:
The wire for the wall outlet runs under the floor, and vibrations are causing adequate power fluctuations to wake the machine up. Not sure how to test for this, though it does concern me about the state of the wiring.
