Given the fact that we can send 580MBit/s over USB2.0 I would not have even remotely considered this to be the problem and find it an incredible shame that audio industry is using such a crippled standard. I have now solved my problem by buying and connecting an analog 5.1 speaker set. Unfortunately I get audible distortions when I turn both the "PCM" and "Wave" mixers to the maximum setting. I wonder if anyone can provide more insight what these controls really do and whether it's better to turn down "PCM", "Wave" or both.
