Hi Mark, I discovered URPMI and set it up, and I am getting the works now for Mandrake, so I won't need Planet CCRMA anymore. I will try the multimedia kernel and see if this helps. I am working on Jack now anyways, I have it setup on my machine now, so I can use it. The reason I used Port Audio was because it works on Windows with DirectX and ASIO and also on Unix. I have been wanting to move to Linux again for a while, it just takes effort to get into setting it up again but I had been using it on and off for a few years, but I don't know the hardcore tools and stuff. I'm just a humble application programmer.... :) See yah.
