I use Audirvanamit explorer dac2 on macpro (Mojave). For some time there is sizzle. This happens with both 3.5 and 3.2.
What could be the problem? Is it a setting thing? I had not changed anything.
No sizzle without DAC.
I wonder if the dac is broken?
Try different port if you’re using USB or try different interface (SPDIF).
I have already tried other usb ports.
The problem is when using headphone connection.
With the other anchluss Better but not 100% clean.
Cable, it was cable. Cable between dac and macpro. I changed cable and now everything is ok.
USB cable has caused the problem.
