My output shows "USB Audio CODEC" ... I tried adjusting settings in Midi setup to no avail.
I think that it is a digital lock problem as the first decimal point in the display lights up just before I get a drop-out or pop. Hold on, I am going to try something ...
... I think I have found the problem. I connected my USB cable directly to the Mac Mini, instead of going through the USB Hub, and the drop-outs have almost completely disappeared. I am now using a 20ft USB cable ... I'll try a shorter one and see if that removes the remaining pops.
I guess the Benchmark has better digital locking as it was able to lock on with my old set up without issue. Anyway, this looks like it is going to solve the problem ... now to spend a couple of days doing an A/B comparison between the two ...
Thanks for your help :-) BTW, how did the Mini / DAC3 combo sound at your friend's house???
