Hello.
I have a Beam with 2 Play1s as surround sound speakers with a Roku and LG tv. Speakers are all on wi-fi.
Streaming music sources will play through all three speakers but I get no sound from the surround speakers when trying to play 5:1 audio. I used to get this problem occasionally but rebooting the router would take care of the problem. I was using Sonos 1 so then I updated to Sonos 2 to see if that would help but now no amount of re-booting will help.
Sonos system info screen shows the beam is getting Dolby Digital 5.1 when I have the problem.
Another new problem happened after going to S2. While streaming music through the app selecting anything on the roku would stop the app stream and then play the HDMI input. Not so any more.It seems that the Beam ignores the HDMI input until I stop the music through the app. Not good.
