Whenever a Netflix show on my Panasonic TV has 5.1 audio I don't get any sound coming through my Gen 1 Beam. If I change the audio to a version without it i.e. from English [Original] (5.1) to English Original], then I get the sound coming through.
When I have 5.1 audio selected, even though I get no sound the Sonos app says it's playing Dolby Digital 5.1.
