ok sorry im not use to this forum things.. im trying to use eventide as a digital device controlled from my DAW via send/return and it´s connected to and from my soundcard. the connection seems ok becurse when i change sample rate in my DAW/ableton live, also the DSP-4000 sample rate changes.  i route audio out from my DAW  through SPDIF but still DSP-4000 seems to get no audio. i have posted a simmular post in the TC.electronics forum(my soundcard) so see if it´s something with the soundcard.
