Aight I see whats going on here :D
I DO appreciate all and any input you guys have in my questions, really, I do.
yes, correct, the issue we are dealing with is crackling all over the place when S/PDIF jack is set to default and device set to output OPT via 24 or 16 bit and 192 000 Hz.
USB connection works like charm, sound is great, no questions asked there.
Ah hah! So does the optical work with lower resolution and no crackling? or do you get crackling via optical no matter what, but it's just a lot worse at higher Hz?
