My NorthStar DAC receives input from my Mac Mini (via COAX). Since a month, HiRes has issues. My input of my DAC starts plinking between 44,1 and 96 as it cant recognize the correct sample rate. Limiting the output in Audirvana to Lossless fixes this.
Im not sure what causes this… Any advice?
Hello @Sander_Kaa,
Can you send me a copy of the “Debug Info” while you have this issue? You can get it in Audirvana Settings>General>Debug Info
Note: By clicking on the Debug Info button, Audirvana automatically copies all its content, all you have to do is paste it in response to this message

Are you using an device to convert the signal from SPDIF to Coaxial?
I’m using the digital output of the Mac Mini to the Optical input of my DAC. I use a cable for this from the Atlas brand. A small plug is used to fit the cable into the mac mini as the optical out is hidden inside the headphone output of a mac mini of the type i have.
So short answer: No, i dont use a spdif to coax converter.
Have you tried with a different cable?
No, unfortunately I dont have any other digital cable.
Worth mentioning is that as soon as I limit the Qobuz output to lossless (instead of HiRes 96kHz) everything works OK. My DAC has some LEDs indicating the frequency of the input. As soon I use HiRes input via Qobuz the LED indicated no input is received, and sometimes shows 96kHz is received, which is the moment some fragments of sounds are audible. I’m no techie but can’t see how the cable can send 44,1 or 48kHz, but not 96kHz.
A testcase which suddenly pops up is whether I can play hires files via Audirvana from my music library. As I also have some troubles in my library currently I cannot play most of my files as the index seems to be corrupted. Will report back when I could test this.
Meanwhile I’m happy to hear other suggestions!
Try disabling the upsampling.
Upsampling is already disabled. I experienced my DAC, which upsamples the received input anyhow does that job better according to my ears.
Another test: higher resolution files from my library are played:
24 bit /48 kHz: good!
24 bit /44,1 kHz: good!
x bit/ 96 kHz and higher: same issue as with Qobuzz.
Also check my Audio Midi setting: inbuilt output, the one I use has selected:
2 channel, 24 bits, 44,1 KHz.
I’m not sure how and if Audio Midi Settings communicate with Audirvana at all, but can this setting maybe be an evil-do-er?
I didn’t have to change anything and I can play files of much higher resolution. It works up to 192KHz sampling rate without issues (max. supported by my DAC).
Have you tried with USB?
Yes, I will do that. Wasnt to fond about USB in the past, but for testing it’s more than fine.
Unfortunately USB doesnt work anymore as OS update broke my USB driver as this DAC needs a driver for USB.
