How did you get the Multimix to work? I've been trying with mine and all I get is loud static in any DAW

On some motherboards you need to replug the mixer in after a reboot or else it gets that weird static/echo. You can use the Midi Audio app in the Utilities to set the sample rate to 48khz instead of 44 too.
