MC24 Settings required to output SACD multchannel ISO to AV receiver via PCM

(1/6) > >>

sensei_russ:
Please help - I'm going round in circles and am now completely lost  :-\

I'm trying to play SACD multichannel tracks (from an ISO) but can't figure out which settings to change on MC24.

At the moment my AV receiver is only receiving a 2 channel signal, although I am definitely playing a multichannel track (the ISO has both).

JRiver running on my Mac Mini connected to Marantz NR1605 via HDMI.

Do I need to change settings in MC24, my Mac Mini or both? I've tried changing both but nothing seems to 'stick' let alone work.

In MC24 I've tried Tools/Options/Audio/Settings - DSP and Audio Format but nothing I select works.


Please help!  :o

Search for Bitstreaming on our wiki.

sensei_russ:
Thanks Jim,

I've done as you said but get an error message:


Playback could not be started on the output 'Core Audio' using the format 'DoP 2.8 MHz 6ch'.

What settings do I need to change and to what for My Mac Mini please? Something in MC24 or in the Macs settings?

Thanks!

Try opening the Audio MIDI Setup app within macOS and setting your DAC to the highest bit-depth/sample rate available. Some DACs require this on macOS to get DSD bitstreaming working.

Ok, I've done as you said. The receiver seems to be showing a multi-channel input now, however I can only hear hiss - no music or other sound. Any ideas please Jim?
