I have some new information about this. I just watched an entire 2h movie with VLC player. Worked nicely, fed DTS to my amplifier the whole time. And sounds even work afterwards.
After, I played YouTube video and got a system message ("blink") and boom! The sound was broken. It seems that simultaneous sounds tend to brake the audio.
