Hey everyone. I posted this question on the Simhub Discord message board as well. I’ve been in the process of building a new rig for the past two months. Up until yesterday I was using ShakeIt for a single buttkicker mini lfe under the seat which worked great. Yesterday, I added four buttkicker mini life’s, one at each corner of the chassis. In the process of setting this up I was using the test channel function in Shakeit to identify which is which. It seemed that the output from the sound card would only work for two channels even though ShakeIt recognized that eight channels were available. I am using a USB sound card (Vantec 7.1) that I suspect may be the issue? Even though ShakeIt recognizes 8 channels there is a warning message to use a dedicated sound card. I have installed the specific drivers for the unit and checked them in the soundcard properties. I’ve ordered an internal soundcard to try but would rather use the usb card if possible. Ultimately I plan on having seven channels - just waiting on a power supply for an amplifier. Another thing that happens is that when you test other channel, either one of the two channels that work will activate. I have swapped cables from the soundcard and all amps, wiring, buttkicker are good. Sorry if I’m unclear On this and thanks for any help.
