I'm using two firewire Focusrite Saffire audio interfaces with Linux.
Stereo audio input/ouput works very well so far. Device and ports discovery also seems to work well.
But I'm limited to using only two channels because all the ports I see in Jack are mapped to the two first. For example, if I output audio to jack port 3 it will sound for the hardware output 1 instead of 3.
I'd be happy to use multichannel as soon as possible even if it's experimental code that sends ad-hoc control parameters.
Having the same for Focusrite Saffire (LE) would also be desirable.
Probably not relevant, but this is my current configuration:
