Hey,
I've had the D03 for about 1.5 years now. It's hooked into a TV where I'm streaming from an Apple TV. And I've had thus issue with Optical port making a terrible noice (see linked video om vimeo). It comes on after a while. Usually when I change apps on the Apple TV. Like from Netflix to HBO or other. I never get this from the AUX port, nor Bluetooth. However, the Bluetooth sounds terrible from time to time - like the sound is cracking.
I've checked the Opt ports for dirt, restarted everything, disconnected Aux + Bluetooth (connections+antenna). No difference.
The Opt port is way better sounding than the Aux - hence why I'd like to get rid off this issue. Any ideas what this might be? Broken amp, broken dac?
Thanks in advance.
