I purchased an Arc, I got it set up. If you have no interest in making use of the Arc to its fullest extent, and just to turn on the TV then it is fine. Otherwise, I have been testing this out for hours. 
 

I am about to pack it all back up and return it tomorrow. The app is horrible. Listen to pandora, and it stops and or freezes. Use Sonos music or radio the same thing happens, useless. Try to use pandora on a device then send it to the arc is also a pain. It’s going back, and I am going back to Bose.
