It now gives you 10 bits by default if your screen can handle 10 bits. For your case, though, you need to set 10 bits in rc.local because CA is hiding the deep colour capability. The official update will replace the testing version in due course.
Hi Graham.
I do not understand. I just tested it and it works fine with nothing additional in RC local.
Hmm. And this is with the CA soundbar? Could you just cat /sys/class/amhdmitx/amhdmitx0/edid and cat /sys/class/amhdmitx/amhdmitx0/config while you are playing a 10-bit clip?
Hi Graham, yes this is the the CA soundbar.

OK, I don’t think you are on the latest kernel. We did force 10 bits just for you but someone with an old display couldn’t get a picture. If you update again, you will have to force 10 bits manually in rc.local again.
Sorry, but we thought your situation was rarer than his.
ok that makes sense, i am fine with forcing via rc local.
What is the latest kernal? i am on 3.14.29-132-osmc.
Strange. That is the latest. Let me check if Sam missed something out…
