TrueHD (Local Downmix)

[Spyderturbo007 19]

I’m playing 4K content with a TrueHD 7.1 track or at least that’s how it’s labeled by Emby on a Shield.  I’ve tried just about every setting I can find but I’m still getting “Audio codec: TRUEHD (local downmix”. 
 

I’ve tried setting the shield in Auto, manually setting each format and setting the shield to never use surround sound thinking that might just be passthrough. I rebooted in between each change and made sure the AVR was turned on first. 
 

for the life of me I can’t get it to not downmix. 
 

Any thoughts?

Do you have CEC enabled on the Shield? Try disabling all those power options in the Shield and reboot so that the AVR is powered first. That fixed it for me and it continued to work after I enabled the CEC/power options again.

Unfortunately everything was already disabled under the HDMI-CEC section.

How is all the equipment connected? Remember, If you use ARC TrueHD is not supported. You should connect your Shield to your AVR if your systems does not support eARC.

Shield -> Sony STR-DH770 -> Epson 5040UB

Both cables are 18Gbps Monoprice HDMI cables. 

Thanks!

Try rebooting the Shield while the AVR is powered on.

No dice unfortunately. I tried that after each change. Left the receiver on and rebooted the shield.  No TrueHD. 

I noticed that when I choose Auto under available formats on the shield that it appears to see Dolby TrueHD. so it appears as though it’s picking it up.  I switched to manual, turned it off then went back to auto and it turned it on.

Then can you please play your true HD item for just a few seconds and then send a log from the app?

I have no clue what I did, but it works. I was just turning things off and on and rebooting. Nothing that I hadn’t already done.  Weird.
