Dolby Digital plus problem

[Peterw66]

Dolby digital plus Sound from sky stream puc is not being sent to the correct speakers.

the sky stream puc is fed to tv a

LG 65QNED916PA then via hdmi to my pioneer sc1223 avr this set up also includes a fire stick and a freesat box  as was the sky  Q box all are  4k all Dolby Digital atmos / plus and feed the sound to the correct speakers. I've always used my own hdmi leads.

sky are suggesting its my avr but as everything else is working correctly it seems to be the sky box.

I tried a full  factory reset which did not resolve the issue.

Any suggestions any one

Your system as set up should  work, all devices in the chain support Dolby Digital Plus etc. I've had a quick look through the online manuals for your TV and AVR and other than the age of your AVR, I'm struggling to see an obvious cause the problem you describe. When you say the decoded sound isn't being sent to the correct speakers, what are you hearing?

In the early days of owning Sky Stream, I'd occasionally get the the front L & R channels only from an Atmos/7.1/5.1 feed being seen by my Denon AVR. The AVR would then apply Dolby Surround (formerly Pro Logic) decoded to the two channels and I'd get audio with no dialogue due to there being no centre channel in the incoming bitstream.

Or are you get a 2 channel mix down of everything being received by your AVR?

Given you are using your TV as the switching device, is the firmware/software updates up to date? (Apologies if I'm teaching granny to suck eggs here). 

You could try setting the HDMI audio output on your Sky Stream box from the default Auto to Dolby Digital Plus, which should cut out the HDMI handshake/capabiliilty negotiation step, in case either your TV or AVR is proving a response the Sky Stream puck is unable to handle.

Hi

thanks for your reply 

I have tried all of your suggestions 

The tv software is up to date 

the avr software is the latest version pioneer provided.

I've been through the tv settings and the puck settings a number of times and even did a factory reset to the puck with no change.

I can't justify buying a new avr mainly on cost grounds and especially as other inputs are decoding properly

It sounds like 

centre speaker sound has shifted to front left all other speakers have various effects an it sounds like it has all shifted left as it were

Does rather imply the Sky Stream box is mishandling the bitstream; other than pulling the power on the Stream puck and leaving it off for a minute or two before reconnecting the power, there isn't much else to be done. The Passthrough audio option should, as it says, pass the unprocessed audio bitstream out via HDMI for external decoding is about the only other lever left to pull.

Is the issue present on all content, both Sky's own and any of the apps/services you might use, or is the issue related only to one or two content providers on the puck?

Thank again 

the sound issue is on all services from the puck.

im going to repeat the factory reset on the puck and do the same on the tv and avr to see if that does anything but I'm not holding my breath as it works fine with the freesat and fire stick 

thanks again for your time
