It runs ok originally, but after about 10 minutes it gives me that errors, and continues with them until the machine is power cycled. I am using the built in Realtek HD card (I know a piece of junk), and it will do this whether i am doing anything or not. In this case I was using Ardour to record a midi application that came with 64 Studio. Any advice as to what a broken pipe is exactly, or how to fix such a problem would be very much appreciated.
