Hi... We are using both digiface and multiface interfaces here at ccrma and we have a (small) problem of consistency in the channel numbering because of the way they are connected. Both cards are connected digitally to digital mixers, but in the case of the multiface the digital channels (which would be the ones users use) are 9-16 while on the digiface the first eight are 1-8[*].

Is there a way to change the ordering in the multiface so that the digital interface is presented as ports 1-8 instead of 9-16? (even a hack to the driver would be welcome) - and preferably one that does not need the default interface to be changed from hw:0 in jack...

The hdsp driver has a static "channel map" per model. Look for channel_map_* in hdsp.c. Tweaking them may help.

Note that the channel_map assignment depends on the sample rate, too. See hdsp_set_rate().

[*] accounts are shared so any configuration you do on one machine for 1-8 will be wrong for the other where the real outputs are 9-16.
