[LAU] M-Audio FastTrack Pro, all four outputs in jack

Hi all - I use an M-Audio FastTrack Pro (USB soundcard) and it's nice - works smoothly with jack - except that it has four audio outputs, presented split into separate devices: * Device hw1:0 has the first two outputs * Device hw1:1 has the second two outputs and the two inputs Jack will only connect to one of the two devices for output, so I can't get four-channel output from my jack apps. This thread <http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg23839.html> suggests that using .asoundrc to aggregate the two devices into one virtual device should work, but for me it simply doesn't, the virtual device never shows up in qjackctl and even jackd from commandline can't connect to it by name. Has anyone experienced anything similar, and/or have any suggestions? Crazy workarounds welcome. Thanks Dan -- http://www.mcld.co.uk
