Line-In Adapter

I just purchased 4 Sonos ERA1 and 1 ERA 300…I’m loving the experience. I would like to use them with my TV until I can squirrel away the funds to buy an Arc Ultra. Is the Line-In adapter the best way to achieving my goal? Thanks in advance.

There will be a 70msec delay on audio-in via any line-in or Bluetooth input on a Sonos device. Line-in quality will be better than Bluetooth but the delay may make the solution unacceptable. 
 

You will only be able to play stereo from the tv; no home theatre 5.1 or other formats would be supported.

    Hi 

    I don’t know your timetable to acquire the Arc Ultra however you might consider a soundbar in the link temporarily. The upside is that you won’t break the bank, and you'll not have the 75ms delay which will be a lip-sync issue.

    Don’t count on it as a “feature”, but some cable box video is so laggy that the 75ms audio latency is a benefit. And I’ve seen it the other way where audio already lags at the cable box exit.

      I already have this issue with my Direct TV service. My wife complains about it but it doesn’t bother me at all. I just enjoy the ride.

      If you use an AppleTV you could just select a stereo pair of the Era 100s as the Audio Output, until you purchase the Arc Ultra.

      Unfortunately I don’t know an Apple TV. I have a 60” Sony Bravia dating back to 2014. Thanks for you response & suggestion.

      AppleTV is an input device to a TV or conventional A/V system. In that respect it is similar to ROKU.
