Normally jackd -Dhw:0 would just give you access to subdevice 0. By using an ALSA "multi" type for jackd's input and output device specifiction, you can tell jackd to create a device combining hw:0,0 and hw:0,1 so that you can simultaneously access both digital and analog parts of a soundcard in Jack. I ran a test yesterday on a 2.8Ghz dual core Opteron 1220, running 'mixxx' through Jack, with headphones monitoring one channel, and spdif outputting the other channel to main monitors. Ran for several hours without any Xruns on non-RT kernel-2.6.32.11-99.fc12.x86_64 ....<div>
