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.

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. 

 

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
