I would like to set up my computer where I can record and listen to my turntables through my computer. However, there is no sound output. I checked the cables and they seem to be functional, I checked the sound of the computer, and the mixer seperately, and they both worked. I have an maudio audiophile2496. It seems like knoppix set this up for me a really long time ago, but I obviously don't use knoppix anymore, and that was onboard sound.
