Hi all, have put this question on the Sony Community a few days ago but so far no replies so will try here:

My gear is:

BDPS6700 Blu Ray player with 4K Upscale

KD-55X8500C 2015 Android 4K TV

HT-RT3 Sound Bar (5.1 Surround)

The soundbar generally works well, can hear the 5.1 doing its thing if I watch a TV channel with 5.1 encoding.

I run into an issue when I am playing a blu-ray movie, when I start a disc all the beginning stuff works but soon as it hits the main movie the sound stops and I have to run the sound through the TV.

The setup is Blu Ray player -> (HDMI) -> TV -> (HDMI) Sound Bar.

I have got the latest firmware running on everything, I have updated the TV to use "enhanced" hdmi on the port the blu-ray player is connected to.

I've tried a few things on the TV like setting the Digital output to AUTO 1 and 2, even tried on the blu-ray player getting it to convert DTS to dolby digital with no luck.

Has anyone got any ideas or able to point me in the right direction? or it just better I take it back to JB Hifi?

Thanks.

I don't really understand why it works like you describe, but some general suggestions:

At the TV, the sound-bar has to be plugged into the HDMI IN socket which is labelled "ARC". Probably only one of the sockets will be ARC-enabled.

If that doesn't work, or if there isn't an ARC-enabled port, try a TOS-Link connection (from the TV to the sound-bar).

With all the cables connected, turn everything off (at the wall) for a while, then turn on the TV, followed by the DVD player, followed by the sound-bar. If that doesn't work try changing the power-up order (there are only 6 ways!). This is in case it's an HDCP/HDMI handshaking issue.

Have you tried going BluRay->Soundbar->TV (ARC)?

I've def got it on the ARC HDMI port on the TV.

Unfortunately the Soundbar only has HDMI-IN so the sound needs to come from the TV. The blu-ray player only only Coax-out for digital and the Soundbar has optical-in.

I've tried killing power to everything and turning it on at the same time as well.

Seems weird the Soundbar is happy doing 5.1 from Vodafone TV, soon as a blu-ray wants to do it there is nothing.

Has the BluRay player got settings you can change for how it outputs its audio?

The HT-RT3 is ARC compatible, I have a RT5 which is similar.

As trig42 mentioned you should try Bluray -(hdmi)-> soundbar -(hmdi ARC)-> TV.

The one I've got only has 1 HDMI port so the above option doesn't work.

Just been going through the manual again and may of answered my own question:

 Depending on the TV, there may be no sound when you playback DTS sources. Set the audio format setting of the TV to “PCM”. For details, refer to the operating instructions of your TV.

PCM is just 2.1 right?

DTS refers to a compression algorithm. PCM is lossless (or close to it) AFAIK and both are independent of channels.

I would still try a TOS-Link connection from the TV to the sound-bar. The TV may let 5.1 DTS through and the TOS-Link can handle that (but I think only 2 channels of PCM). Probably more flexible than the HDMI ARC.
