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.
What technological gremlins haunt you?
My partner streams my Plex to their whole house by way of some sort of coax input device. I’m not really sure how it works but it uses the house’s cable lines to stream whatever from an hdmi device (in this case an rpi) to a unique channel.
Works great everywhere and for every device plugged into it, except a 9-ish year old Samsung tv. On that, the audio cuts out for a half second every 30 seconds or so. Without fail. No change to the picture, and an older Samsung tv handles it fine. We’ve tried everything we could find - including heavily tweaking Plex, and rebuilding the rpi entirely - short of replacing the tv, no dice.
Interestingly, no other stuff through that rpi on that same configuration has problems on that tv, so like we can load the retropi and play games and the sound works fine. It’s really just that one app, through that one method, on that one tv. So weirdly specific.
