LG CX & Sonos Playbar


Standard Member
Please bare with me...

I recently noticed that Sonos have added DTS to the firmware. Upon checking this I cant get my sonos to play DTS, I presume this is down to the TV not supporting DTS?

I have the LG CX connected to Xbox Series X via HDMI2 Earc and get Dolby Digital 5.1.
Apps like Plex on the TV also get Dolby Digital 5.1.

But no mention anywhere about DTS?

Assuming the TV will not Pass or Output DTS as multichannel PCM you would need a suitable Source device, such as the ATV 4K, the required Subscriptions plus the HDFury Arcana.
