I'm not sure if this is related to my wiring, DAC or XBMC itself but I figured i'd post here to share my findings.
I am running XBMC on my xbox 1, with 480p component video output and audio via a toslink cable to my external DAC. Whenever I go through XBMC's menus (making a click noise) my DAC's signal error light comes on for a second. Playing music and video it is fine, but if I use XBMC's volume control I also induce an error/distorted signal to the DAC aswell (it does not show this at all with any other devices).
I originally thought this was a simple wiring problem, so I have changed both the toslink cable and HD component/optical lead. Each configuration is showing the same problem (I've also tried another XBOX and a fresh install of XBMC).
The strange thing about this problem is, if I use an old composite+optical break out box (the kind which you wire the video/audio yourself). I do not get the same issue with optical output (any volume level or format from XBMC goes to the DAC fine). This is very odd, the only thing I can think is that the breakout box has a better implemented toslink output? Since it is PCB mounted on a board it may be more stable or buffered somehow? Still, from my experience it seems to be far more stable if you use the optical output than on the version 2 (cabled) HD pack.
Has anyone else had a similar problem? These cables I have used have all been 3rd party (Sintech and Konig for the cabled component/optical and a "play on" break out box). I am currently awaiting an official MS HD set (the cabled version) to see if I get the same problem.
