[LAU] Multiple M-Audio Delta 1010s

I was wondering what the current status is of using multiple Delta 1010s with jackd. I have seen several references to an .asoundrc for this kind of a setup, but I have not seen anyone say how this is working for them. I currently have a single 1010 installed in a 3 GHz P4. While running at 5 msec latency it is running at about 6% CPU utilization with jack and Ardour2 running. How much does a second card add to the CPU load? Also, can xruns be avoided under these circumstances? I'm planning on using the machine for auxiliary processing during live performance. I know that RME cards would be the best option, but I really can't afford the card and the A/Ds. BTW: I had a significant amount of problems eliminating xruns on the machine. I started by moving from KDE to IceWM, but that did not improve things. After that I went from a normal kernel to the 2.6.22 real time kernel in the Gentoo pro audio overlay. That also did not seem to help very much. Even at 100 msec, I was still getting lots of xruns. I then turned off hyperthreading and added rtirq. These changes helped, but I could still generate xruns by just typing in a terminal window or moving the mouse. The thing that actually solved the problem was changing from the ATI Mach 64 on the motherboard to a NVIDIA 5200. That seemed to be the magic. I can now run Ardour with no xruns at 5 msec latency. -- Terry Hull - President Network Resource Group, Inc.
