A new Sony Bravia TV
A sonos beam , connected via hdmi arc
Two play 1s set up as surround by the sonos app
A Phillips DVD player connected to the TV by hdmi
Everything from the TV is routed through a sky box
When the DVD player is connected to the TV, the TV does not play through the beam at all but the DVDs play in surround sound through the beam. As soon as I disconnect the DVD player, the TV plays through the beam but only in stereo, not in surround sound.
What have I got configured incorrectly ? I shouldn't have to keep unplugging the DVD player should I ?
