I have a new AM6B Plus here. Would really appreciate some help!
My goal was to replace an Odroid N2+ with something with DolbyVision compatibility. I am not so bothered about achieving AV perfection (player led vs TV led), more just the ability to play (most) DV files back, should I need to.
I followed the guide ([Guide] S922X-J (Ugoos AM6b+) CoreELEC installation and FAQs) to install it.
- Installed latest nightly ng
- Copied device tree to
dtb.img - Copied
dovi.ko(and have re-done this just in case of d/l failure) - Installed as usual etc.
- I installed to EMMC (perhaps should have waited with this) and set to HS400
- I am testing with various DV test files plus
& some downloaded DV things (episodes and movies etc) - (I have not tried the CPM build)
Hardware:
- TV is a Panasonic GZ1000 OLED (a bit older now, and only offers player-led DV I have seen, except when using in-built apps)
- I have an AVR (Denon X2700H), but note I have tried with and without this (i.e. Ugoos player directly connected to TV) - with identical results.
- Ugoos AM6B Plus 4GB/32GB
- Excellent HDMI cables that have no issue with an other 4k/HDR/60Hz etc content.
Issues
In general all normal things are working well, but the two main improvements over the Odroid I was looking for are both not right!
- Dolby Vision is not working - classic green screens.
In the CE system info and logs, I can see that DolbyVision support is detected. I can see DolbyVision options in the CoreElec settings, although it shows only ‘player led’ as an option - and that only as a greyed out switch (which I guess is correct given my particular TV).
When I play back DV content, my TV definitely switches to DV mode with the logo etc. showing - however it looks just like when I play a DV file on the ODroid - green and purple craziness.
I have checked all TV and AVR settings (and there isn’t much - just the DV is turned on in both basically). I was rather expecting it to ‘just work’ at this point given the experiences of others…and again, I have tried direct connection with the same results. Not sure what to do/try??
The Ugoos powers on immediately when plugged in.
EDIT - I managed to fix this by using ‘reboot to EMMC/NAND’ then in the Ugoos interface going to Settings → Device Settings → and changing the option to keep the device powered off when plugged-in. My Harmony 650 remote wakes it up and puts it to sleep fine and the player no longer auto-boots immediately on plug in…
(Would probably be a good addition to the guide/FAQ and ideally this would be done before the Kodi installation reallly…)
