Title: Can't play DSD256 files from Mac mini (2018) to Mytek Manhattan II DAC via USB
Post by: swizzleD on March 18, 2021, 06:55:46 pm
Greetings!

I have a 2018 Mac mini whose OS I recently upgraded. At the same time I upgraded to MC 27 (27.0.62). Now I can no longer play DSD256 files but DSD64, DSD128, and PCM work fine.

Before my upgrades the Mac was running Catalina with MC 26 and everything worked fine. Now two things are different. I did a clean install of Big Sur and then installed MC 27 and configured it from scratch. As before the Mac is still running via USB to a Mytek Manhattan II DAC (no changes there).

In Options, I've got the following parameters set:
Attached is the error message I get every time I attempt DSD256 playback. Could Core Audio be messing me up?

Can anyone give me any pointers on where to look to resolve this problem?

Many thanks!

Kurt

Looks like, according to the specs and manual of your DAC, that the Mytek Manhattan II only supports up to DSD256 via native DSD and up to DSD128 via DoP. Unfortunately with macOS and Core Audio only DoP is supported, so you're likely going to limited to DSD128 on macOS. There's no way around this on macOS unfortunately, at least not without converting from DSD256 to DSD128 which is a lossy process (as it has to go through a PCM stage in the middle).

If you want DSD256 you'd have to use it from Windows or perhaps Linux (assuming the Linux kernel supports native DSD for your DAC).
