My ARC doesn't work with DTS

I thought I would test the new update that supports DTS. 

 

When I feed it a DTS signal from Plex, it is silent. 

 

If I disable the DTS audio in plex, it is transcoded to Dolby.

 

My settings are all correct as far as I can see.

 

I have tried DTS regular and DTS HD and neither work.

 

My system and TV are both up to date.

    @Andrewnoob If you are using the LG CX, it doesn’t support DTS audio.

    Only DTS is supported on Sonos HT products, not DTS-X or HQ. Anyhow, assuming you’re not using an A/V device with an audio extractor, it might be the connected TV that does not support or pass-through the DTS codec. I would perhaps check with the manufacturer, or elsewhere online like rtings.com to try to discover if that is possibly the case

        Thanks, good to know - eARC seems a bit flawed. 

        I don’t think there’s a way to get PLEX to output PCM is there?
