Is it true all HiFI Rose products are Stereo Only even on the HDMI port?
RS130
1 HDMI OUT is Video only, to be used with RoseTube.
1 I2S HDMI OUT for Audio to a DAC (2.0 only).
@ROSEHAN can you pls confirm?
The RS130 sends both audio and video, however, you have to switch to HDMI output. Video is sent along with HDMI when on another outputs.
I would also like the answer to getting MCH files to play, for now I am using my OPPO for this.
@joyofmvid another reason to use Roon > Rose. Roon streams MC to my receiver over HDMI up to 7.1 PCM.
It bypasses HD audio formats such as surround sound sources to audio receiver through HDMI without decoding.
@ROSEHAN
Do you mean, RS130 “bitstreams” 5.2 & 5.2.4 music on HDMI port. If so, that would be perfect for me.

I found thhe answer at Playing .mkv files from an rs130 - #7 by HMANAZ
RS130 Bitstream’s 5.1 & 5.1.4 audio
I’m now a happy puppy! 
So @ROSEHAN, Rose devices do support multichannel? Now I am confused, @joyofmvid that was my message. I am seeing conflicting info, still unable to get pass-through to work. I have MKV multichannel files I wish to pass through to my oppo players HDMI in. If I play them from Rose, I only get Stereo over HDMI with pass-through enabled. If I play them from my Oppo (terrible UI) I get MCH.
@ROSEHAN
I don’t expect RS130 to decode multichannel audio but does the RS130 passthrough (i.e., bitstream) 5.1 and 5.2.4 audio to the receiver? If no, then what does HDMI Passthrough do?
