Here is my current setup :
27" late 2009 iMac > USB to NuForce U192S > Optical to Schiit Gungnir > RCA out to Rega Brio R Integrated Amp
There is no sound above 96 kHz sample rate. The blue & white LED between 192 & 176 is on the NuForce U192S but no sound. All other bit rates are fine. I can see the sample rate change in the Audio MIDI setup.
Is there something I'm forgetting to configure? How do I resolve this?
