I have a number of Sonos setups connected to my LG TVs via the optical cables.
The TVs connected to the Soundbars keep their volume settings when a TV program is paused or the TV is switched on for the first time. The TV that is connected to the Bean G2 drops the volume level to 0 after a few seconds on pause or when between the TV being power cycled. If I use the TV speakers I don't have the issue, its only happening when used in conjunction with the Beam.
Anyone have any ideas on how to fix this ?
