MC24 Settings required to output SACD multchannel ISO to AV receiver via PCM
blgentry:
To get MC to convert DSD to PCM you need to do a few steps. This won't be step by step perfect exact, but it should be close and get you started in the right direction.
- Turn off bitstreaming: Tools > Options > Audio > Settings > Bitstreaming > None
- Set your output to be 5.1 or whatever your real number of speakers is:
Player > DSP Studio > Output Format (make sure it's checked) > Channels > (set number of channels here)
> Output Encoding > None
Good luck.

Hi Brian,
Thanks for your message.
I've followed your instructions and now get the following error message:
Playback could not be started on the output 'Core Audio' using the format '768khz 6ch'. I've tried changing the bit rates but it always reverts to 768khz.
Also...
I can get bit-streaming to work playing flac multichannel files, however only via my Mac Minis 'built in output' and only with FLAC files it seems. The HDMI output cannot be selected. If I try to play SACD iso's then there is no sound but I'm guessing that's because the stream cannot be output through the 'built in output'.
It seems in both cases the problems are due to my Mac Mini's audio output setting.
Apologies if this is all blindingly obvious to anyone reading, as I stated before I'm completely lost!
Any help with a simple way to play SACD ISO's via my Mac Mini and Marantz NR1605 which can stream DSD? I don't mind if MC24 bitstreams or does a conversion as long as I can hear the the music in multichannel as I would when using the physical discs.
Any help - please?

I think you are very, very close! Your receiver almost certainly can not accept 768kHz audio. It's probably limited to 96kHz. Maybe 192. Here's how to fix it:
Open the DSP Studio again: Output Format > Sample Rate
Now find 768kHz as input and set the OUTPUT to be 96kHz. Or 48kHz if you'd like. This will tell MC to downconvert that super high resolution to a resolution that your receiver can handle.
Once you get that working, you should probably set ALL high sample rates (above 96kHz) to 96, so that it can play whatever you happen to have in your library.

Hi Brian,
Well I 'seem' to have things working when using Bitstreaming. Previously I had 'DSD' selected under Bitstreaming, I simply changed that to 'HDMI' (doh!) and things started working. I'm getting optimistic now but trying not to get over excited just yet 8)
For some reason my Mac Mini's audio device output seems to switch between 'Built-in Output' and 'HDMI' at it's own will when I go back to check it. However when it is on HDMI (and I can click the options there-in) - please see image here: https://imgur.com/a/GR6Fu1Q
I'm guessing I need to choose the 48.0 kHz 8 Channel 24bit setting? Other settings I tried altered the pitch of what I what I was playing.
Does that sound right?
P.S. DSP studio/non-bitstreaming just doesn't seem to work for me - aside from the FLAC files...
blgentry:
For bitstreaming of DSD, I'm really not sure how things should be set in Audio MIDI Setup. I've been told that you are supposed to choose the highest available there (which would be 192kHz in your case). But I don't actually know. Again, I've also been told that bitstreaming DSD, via HDMI, does not work from computers. I don't have experience with it myself. Sorry about that.
I'm relatively confident that you can get MC to send audio from ANY file type you have, via HDMI, to your receiver, without bitstreaming. I could be wrong of course, but I'm pretty sure you can make it work.
Screen shots of your DSP Studio Output Format window might be helpful if you want to pursue that path.
If you want bitstreaming DSD to work, perhaps someone else here can offer more suggestions.
Good luck.
Brian.
