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 digital tv reciever cannot receive a large range of channels when a mini pc, in off state, is plugged in on the same switch. It works fine when the UTP cable is not connected, it works fine when the mini pc is on, also fine when the pc had no power at all. Distance between pc and receiver does not matter, neither does the configuration of cables in the switch. I’ve given up on it, but sometimes the issue disappears for months, and then comes back for a while.
