I did everything in your email. But it appears that I am still not correct. I connected a stereo output from my PC "Headphone Jack". This went to CH0 - CH1. I used USBi to 1452. I connected a set of ear buds to the output. Out 1 CH0 CH1. The sound was on for less than a second then I heard a crackle then no sound. I tried a parametric equalizer. Same thing. I hit the hardware reset and the sound is working. I have no control because of the hardware reset. Is There a voltage limit on the input and output. I watched the video on the website. There was a demo using filters. I heard the sound going up and down at the different frequencies. I am using the latest version of SigmaDsp. This is a beta version.
I am stumped
