Audio from Jack is "Bitcrushed"

[infelicitatis]

I have Set up Jack and it kinda works, i have it running on my asio:digi rack 002. I can pass sound from A to B but it all sound lie very bad and crushed to death. I tried adjusting driver, buffer, period, sample rate, but it dont work. 1 out of 100 times it randomly funktion correctly, and my audio is clear and sharp, but if i close port audio, reopen it, without changing anything, the problem is there again.
Also i noticed: When i change the sample rate in the setup, the LEDs which indikate the sample rate on my interface dont change, it always stays at 44,1 khz. In the "Status" tab it also doesnt change.
Running as administrator doesnt help. compatibility Mode doesnt help, settings doenst change anything... im out of ideas.
