My Sonons Beam was connected to my Sony TV (XBR-65X900F) via the HDMI ARC and had been working fine since I bought it back in October. Suddenly, yesterday morning it no longer works with the TV. It does work to play music, just not the TV. I have checked the TV connection, reset the Beam, reconnected it. I have also checked to see that the TV recognizes that it is connected, and it does. However, when it changes to external audio speakers, no sound comes out. ????? I have absolutely no idea what happened to disable the Beam from working. Now the TV recognizes the Beam and tries to switch audio to it, but there is no sound, so I have had to completely disconnect from the TV to get the sound to work on the TV. The only thing that I can think of is that there was an update somewhere either on the TV or Sonos that caused the issue. Does anyone have any ideas?
