I also just bought a Sonos Playbar and love it. All has gone well and easy except for the annoying problem of "not available" messages any time I change the volume with either of my two remotes that are paired to the TV and control the Sonos volume without any problem. External speakers are off. Looked all over the settings and the blogs.
Please post if you find a solution.
I just purchased a soundbar and paired my TV remote to the soundbar, so as to adjust volume on the soundbar with my TV remote.
In order to not also adjust the volume on the TV itself as well as on the soundbar, I set the sound to go to "External Speaker" (changed from "TV Speaker"). So, no sound comes from my TV speaker--it is all set up to go through the soundbar.
However, when I adjust to volume up or down with my TV remote, the sound is adjusted successfully, but I also get an ugly "Not Available" dialog box on the screen. It stays up there for several seconds and is unavoidably distracting.
Does anyone know how I can get rid of the "Not Available" notice?
