Received my NFB 12.1 last week. Here we go...
Can't get it to properly utilize USB from my standard issue 2010 MacBook Pro without artifacts and distortion. Cables are good. In Audio MIDI settings I have played around with changing the output (44khz, 96khz, 16/24, etc.) but it still comes through sounding like a cheap voice shifting effect with aliasing.
The USB works fine through my HA INFO98 amp. Plug and play.
I will get a toslink cable today and see what happens.
Also, I use the unit as a preamp with a CD Player via SPDIF and it outputs a loud burst of white noise crackle through headphones or speakers whenever the CD play button is pushed. I tried it with a second player and the same thing occurs. It is not the cables - I tried many. Both players also work noise free with the HA INFO.
Any ideas appreciated. This is a quirky unit to be sure. I just need to be certain it is screwy before I risk returns costs.
