Playbar suddenly not playing TV audio - Still works with streaming.

My Playbar suddenly stopped working with TV audio this week. I have an LG UK6570AUA using optical out. This has worked without issue for 2 years. If I go into the app I can play music. It will not recognize the TV input. I have this Playbar set up along with a sub and two surround speakers.

Strangely when I try to use the volume up on the remote, the LED on the Playbar does not show anything. But when I press volume down, the LED blinks. Regardless if I go into the app it does not see that there is a TV source and raising the volume does nothing.

So this happened for the first time last Thursday. I reset all connections, power cycled a few times, and eventually the playbar came back. Today (Saturday) same problem. I cannot do the same kabuki dance with all the wiring again. My wife is pissed. I had to go back to the TV speaker.

I have seen other posts about this problem. Seems like a silly issue to have.

Please help ASAP.

UPDATE on this problem. I may have solved the issue.

I purchased some compressed air and a brand new optical fiber cable. I blew out each optical fiber port with air and installed the new optical fiber cable and confirmed that it snapped into place. So far I have not had the audio failure problem.

It is possible that either the optical transmitters/receivers were dirty with dust - and - it is also possible that one or both of the fiber cables I used was scratched just enough to fail from time to time.

For now I think we are in good shape. It would be helpful if the optical receiver could provide a singnal level of the input, because optical fiber input levels are very sensitive and if in fact the fiber was scratched or not seated, then the level would have been too low to properly receive. But without this type of signal level information, I had to replace the cable, blow out the ports, and hope that maybe this is it.

So for now we are back in business working fine. For others having this problem, make sure you have blown air to clean out the optical ports and have a nice new cable with covered ends that has not been touched by kids dirty hands or left in a drawer.

Thanks

Patrick

OK. The problem is occuring right now after working for 2 days. Time is 3:05 ET. I submitted the diagnostic around 3:00 ET. I have been playing television for 5 minutes and I just submitted a diagnostic.

Please investigate the diagnostic and let me know what you see.

To repeat some of the details:

The DOWN volume control button press results in an LED response from the Playbar

The UP volume control button press results in NO LED response from the playbar.

From experience once the problem disappears, the volume UP button will come back to life.

EDIT - 3:10 PM

I revised the sound settings to change from Optical to TV Audio - then back to Optical and now it works. So when I switched back and forth the Playbar started to work.

I will submit another diagnostic right now.

Hi I had almost the same issue where everytime I turned my TV on my volume was at zero. And after a hour of looking through the sonos app I stumbled across a TV autoplay button that was off. I switched it on yesterday and it seems to have fixed the problem so far.

Was there ever a resolution to this problem? I’m all of a sudden experiencing the same issue with my Playbar. I’m witnessing the same things with the Playbar LED status light while trying to control the volume up function. I temporarily installed a Visio sound bar with the existing optical cable and it works. I’ve reset the system and reconnected everything to no avail. Playbar still won’t play any TV audio. I’ll try a new optical cable, but from reading this thread it sounds like there may be something else going on. Any help or direction would be greatly appreciated.
