No Sound From Kb37, And I Can't Switch Back To My Default Sound Card? O.o in Computer Audio Setup and Troubleshooting Posted December 15, 2013 Hey guys, I also have a similar problem. I just got my kb37. I can play and record guitar just fine with it but there's absolutely nothing as far as the keyboard goes. I have it connected via usb to my pc and I use riffworks standard daw. Any advice or ideas would be greatly appreciated! Ty.
