Sound suddenly stopped working

Having a very weird issue. Wanted to watch an mkv file yesterday, in wich the audio played fine before. Upon playback the audio was just “trickling” through in very short “choppy” bits. Re-setted the box and now there’s no audio output anymore. I’ve tried everything from different audio options to cables (using HDMI) and nothing. Latest firmware is on the box. Any clues?

Re-setted the box ? does that mean you did a factory reset ?

Setup > System > Device Reset > Reset All Settings Back to Factory Default

exactly

try another TV

Sure, i have another tv laying around ;)…there are no problems with the HDMI ports on my tv

oddly enough sound works when i hook the box up via breakoutcable.
