Did 6 channels work with that patch? (possibly with a wrong channel order) Also, could you provide the patch? (so that I won't ask you or anyone else to test unnecessary stuff :) ) I wasn't able to locate the original thread in archives. > Since I just moved to jack/rca cables I'm in no hurry anymore, but is > there any reason why the driver cannot work with more than 2 channels?
