Z3000 pro: are both HDMI outputs equal in terms of audio capabilities?

Hi!
Is it possible to get DSD output from main HDMI output? Or it's only supported by dedicated HDMI Audio output?
In audio settings there is DSD option for HDMI Audio, but seems nothing for main. And when connecting receiver through main HDMI, I can get only PCM audio...

 

I will answer my question myself No, those HDMI outputs are not equal in terms of supported audio format. And if you have a decent AVR, it's better to connect it through dedicated audio HDMI output of Zidoo and leave main HDMI for video image only. Of course that create some inconvenience as you can't anymore use onscreen menus of your AVR. One solution - connect AVR HDMI output to another HDMI input of TV/Projector.
I've tested this with a rip of SACD Pink Floyd - The Dark Side Of The Moon.iso. When played through Zidoo main HDMI, it's automatically converted to PCM and even worse, it's break up for few seconds on some tracks... When switched to audio HDMI - everything played smoothly as silk, native DSD64 2.82MHz multichannel!
So, it's seems that recommendations that I saw in many threads here, where it is recommended to connect everything through main HDMI, was incorrect.
