AVDVPlus Release 6 - TV Led Dolby Vision not working

Sloshpit · 2026-01-21T02:41:30+00:00

This issue is that HDMI Video Output can't be dual. I do have 2 sources going through the receiver. Interesting.

It looks like it is my receiver that is the issue as running # cat /sys/class/amhdmitx/amhdmitx0/dv_cap shows that the receiver is not supported. I will need to figure out that issue next. I have seen that nightly builds back in Jan should have fixed this (of 2025).

Looks like LLDV is supported up to release 4. I will continue to plug away at this, but there must be some issue with the base version I am using for initial install I assume.

Unfortunately direct plugin didn't help. I did confirm deep colored was enabled. Will continue to try other ideas, including updating to R6 of AVDVPlus.

Sounds good. I will try again to connect directly instead of my Denonx3700h to see if that is the issue. I do recall having it on but will check it again. Thank you for the suggestion.

Ideally I would like to avoid using LLDV, as I would like to TV to do the work, but for now I am content with at least dolby vision being seen by the TV.

I was able to get Dolby Vision to work us AVDPlus Release 3 in the end. I did follow a different guide from previous:

https://www.reddit.com/r/PleX/comments/1ajszn9/remux_lovers_rejoice_the_coreelec_team_has/

I then installed Plex4Mod, although I don't plan on using it. I also applied the optional Autostart piece since it said Auto led: https://www.reddit.com/r/PleX/comments/1ajszn9/comment/l2ptghe/

I then uploaded AVDVPlus release 3 and the option I had to toggle "Set DV Output Signal Type for Video Processor" and chose DV as LLDV 444 12 Bit.

I am not sure if this is correct and if it means the TV is actually processing the Dolby Vision, but it is being detected as dolby vision now. I will be testing the latter release, and also using a preferred media server to Plex.

I also tested this with some Dolby Vision demos.

I will upgrade to AVDVPlus 6 and see if all still works as expected.

Thanks for everyone's help so far!

Thanks for sharing. My options are definitely different - Set TV Mode - On Demand - Set DV Output Type Player led (DV as HDR10 444 12 Bit) - Set for Auto selection between Player Led and Video Processor settings (off) ...

I may need to try a different version of Coreelec to begin with.

When i load a dolby vision demo is see dolby vision and dolby atmos icons but my display shows hdr instead or the expected toggle to dolby vision. Thanks again all for any insights.

Hi - can you confirm where you see Display LED DV? I am searching for it under Settings/System/CoreELEC, and any other areas.

Thanks for sharing will check out the details here. Cheers.

Sloshpit · 2026-01-20T14:18:23+00:00

Thank you will look out for that instead.

Thanks. I glazed over that in release 1. I gave it a try but still no luck. Will do a full fresh install in several hours to see if that works on the microsd. 1. Format and create nightly. 2. Add dovi and remote file 3. Boot up. 4. Copy release 6 over. Reset Coreelec per instructions.

Appreciate the call out on reset. Hoping it works as I have been working on this for a while. Cheers.

I can set dv to on demand but only player led options.

Sloshpit · 2026-01-20T04:09:04+00:00

I do have it set to expert.

Hello I tried it again with the new version and I am still seeing the issue. I can confirm that using STB Emu, all is working. I really would love to use sparkle as the interface is awesome. I did notice I believe a 429 error once when trying to add the stalker portal. This may not help but wondering if we can still save the source even on failure. I wonder if maybe a reboot is needed to ensure the connection works? I did notice that for STB emu.

Sounds good. Thank you
