Hi,

Is their anyone successfully send a Multichannel DSD file(*.dsf) over HDMI to a receiver and successfully got multichannel DSD output using JMC? 

I am having SONY SACD player BDPS-6700 and this is connected to Yamaha CXA5100 preprocessor. I am able to play a 6 Channel DSD (*.dsf) file using SONY BDPS6700 to YAMAHA 5100 using the HDMI bitstream option. Yamaha Shows the input file as 6 CH DSD and plays 6 CH DSD.

When I tried to play the same  6 Channel DSD (*.dsf) file from PC using JMC which is connected to Yamaha pre pro CXA5100 I am not able to play 6 CH audio. JMC is always converting my 6CH DSD file to 2CH DOP.

Any help will be appreciated.

Regards,
padma

Try setting the Channels to "Source number of channels" in DSP Studio Output Format

Graphics cards, which are in charge of the HDMI port on PCs, unfortunately do not support DSD. As such, there is no reasonable way for any software to send DSD over HDMI on a PC.

In addition to what Hendrik said, the same also applies to Macs and SoCs like the Raspberry Pi and things like Intel's NUCs, you can't use/send DSD over HDMI with them unfortunately because none of them have any driver support for DSD in the GPU's drivers.

I am not an HDMI guy, but the HDMI standard supports 176 KHz and 352 KHz PCM.  So, if the graphics drivers supported those sample rates, theoretically, you could send DoP over the HDMI, at least for DSD64 (1x) and DSD28 (2x), since  DoP for those  is 176 KHz and 352 KHz PCM.  Unfortunately, most receivers that accept DSD over HDMI only process native sample rate DSD, not DoP. The HDMI support on those receivers were designed years ago to get DSD signals from SACD players, which only sent native sample rate (2.8 Mhz) SACD. So, DoP is not an option unless some manufacturer makes their receivers understand 176 and 352 KHz DoP. 

Neither native sample rate drivers on PCs nor DoP support on receivers is likely to happen, given the low volume of DSD music, although there are always rumblings that NVIDIA might do it in their drivers.

DSD over HDMI

I have sent DSD just fine to a Yamaha CX-A5100. I can't remember if it was multi-channel or not. You have to connect the CX-A5100 to your network and stream to it via DLNA from JRiver to the CX-A5100.

Tried that too...Stereo only possible that too PCM !

DSD over HDMI

Again, it's not possible to do DSD over HDMI from a PC/Mac/etc. so it's not going to work that way and it definitely won't work when DSD bitstreaming is enabled. DSD over HDMI from any sort of computer won't work at all.

DSD over DLNA (either native DSD or via DoPE whichever it supports) is what you should be looking into, which is what mojave did and is referring to above.

To do DSD over DLNA using DoPE, you check the bitstreaming box and to send native DSD sample rates over DLNA you uncheck the bitstreaming box.

I would use PCM on HDMI.
That works with multichannel.

How does that make any difference when it's the PC's graphics driver that does not support DSD?

Sorry.  My error.  I forgot to note that I have been doing this with conversion to PCM in DSP Studio.
