Issues with DSD256 and Brooklyn DAC+

DSD over DoP is the only possibility to play DSD on the macOS platform. Exception is if the DAC vendor provide special drivers. 

To package DSD128 in PCM, you need on the macOS platform 384 kHz PCM sampling rate. For DSD256 it would already be 768 kHz.

So your DAC must provide a pcm sample frequency of 768 kHz to play DSD256 on the macOS platform.

Ah, that explains why the DAC's I've seen that support DSD generally don't go as high with DoP.

Hi, I failed to play a DSD256 file purchased from HDtracks using Brooklyn DAC+.  Can you advise the appropriate setting on JRiver to make that work. I am currently on version 26 installed on desktop PC running Win10.

Enable DSD bitstreaming.

It was enabled. Here's the error message when attempting to play DSD256 via Brooklyn DAC+.

"Playback could not be started on the output WASAPI using the format DoP DSD256(4x) 2 ch.
The output format may not be supported by your hardware" .

No such problem exists when playing DSD128.

Awesome Donkey:
Looks like it requires native DSD for DSD256 playback, not DoP which you're currently using (as your DAC doesn't support a PCM sample rate high enough to get DSD256 working with DoP). If I had to guess, you'll probably need to install the driver for the DAC which (hopefully) has an ASIO driver and then switch to ASIO from WASAPI within Media Center's Options > Audio > Audio Device. Also make sure the DSD bitstream in DoP format box isn't checked in Device Settings after switching to the ASIO output in Media Center.
