mk3 hybrid input noisy (similar to bitcrush effect)

[greitzlechner]

after installing the soundcard and starting ableton everything was very slow and i couldnt hear any sound from the input or from audioloops that i used in ableton.
after setting the Sample per Buffer Size to "64" the soundcard started to work. i recorded some stuff with it. but after a few minutes of recording the sound started to get noisy (sound is very similar to bitcrusher). i tried it a few times with different inputs. i disabled the input and enabled it again, after that it worked again. but as soon as i start to record anything the noise comes back. its also in the recorded file then.

i am running on win xp home sp3 / Intel Core 2 CPU 6400 2,13 GHz, 2 GB RAM

i installed the soundcard also on my laptop. everything worked fine, so it cant be the soundcard or win xp
