Is anyone having noise and cracking issues through the optical input? Through USB it works fine, but through the optical everything I play has a lot of noise and cracking (similar to an old bad tape/vinyl recording.
Tried diffent sources (PS4, CD player), different cables, different AC outlet. I am 100% sure the fault is in the DAC the other devices when plugged to my AVR directly have no noise.
It is being used in Europe, if that makes any difference since the power supply says it works with 240V as well and I just replaced the AC cable connecting to it (and anyway - USB input w. PC works fine, no noise).
