Hello,

I bought the Beyerdynamic 990 pro headphones with the DAC FiiO E10K Olympus 2

The Headphones work for like atleast 30mins and after that the sound is just gone and when

the unplug and plug it in again i have no sound..

I only have sound again if im restarting my PC

Idk if you need this but i have encoded format :

DTS Audio
Dolby Digital

with 48.0 kHz
 
Did you contact support for the headphones or the DAC? Need to test headphones on another system to see if they work OK there, or maybe without the DAC if your audio card can drive them properly.
