Help with version 30 playing DSD on Mac, was working fine
« on: July 10, 2023, 04:00:15 pm »

I'm using JRiver 30.0.97 on a 2012 Mac Mini (OSX 10.15.7, the latest for that computer), connected to a Benchmark DAC3B via USB.  I've been playing all PCM resolutions as well as DSD/DSF for some time now (years) with no problems.  Recently, when I play a DSF/DSF file, I get no audio output from the DAC, only a very faint hiss, and the DAC LEDs indicate its receiving 24/176, not bitstreamed DoP.  As an interesting note, when I play a 16-44 redbook file, the DAC now indicates its getting 24 bits from JRiver, previously it correctly reported 16 bits.  All PCM sample rates play fine.
Debugging:
1. I've swapped out the USB cable, no change.
2. I tried using and older version of JRiver (23) on this Mac Mini, and I get the same problem - JRiver thinks its outputting bitstreamed DSD, but the output is silent, so I'm thinking maybe some Mac system setting is the issue.
3.I then moved the DAC to my older backup 2009 Mac Mini (OSX 10.11.6, latest for that machine), which has JRiver 20.0.126 running, and DSD/DSF files play fine in bitstream/DoP on that machine.  Also, 16-44 files correctly show correctly as 16 bits on the DAC, so I'm pretty sure the problem is NOT the DAC3.
Settings:
There have been no (intentional) changes to the 2012 Mac Mini setup, and the relevant options look normal: Bitstreaming is set to DSD and DSP/Output Format
 sample rates all set to no change, and Output Encoding set to none.
Any suggestions what could be causing this DSD playback problem on my 2012 Mac Mini?
Thanks,
Mike

Make sure you have both system volume and MC's internal volume set to 100%. Also make sure in the Audio MIDI Setup app that you have it set to use the biggest sample rate available. Those are needed with some DACs in order to get DSD bitstreaming working.

Very helpful!  I checked the system volume and it was a bit below max, corrected that and its now working fine with DSD.  I also changed the Midi setup to the max sample are just to be safe if I ever change DACs.
Thanks very much!
