[linux-audio-user] jack doesn't see my digital I/Os

i used jack with my Echo Gina24 (which has 2 ins, 8 outs) since today, withous problems. just today i bought an ADAT I/O box (Fostex VC-8). in the Echo Mixer i can see, hear and control both analog and digital channels. but when i start jack, i only see two analog inputs, and eight analog outputs. where did my new digital channels go? if i force jack to use 10 input channels and 16 output channels (VC-8 has 8 ins and 8 outs), jack says: loading driver .. apparent rate = 44100 creating alsa driver ... hw:1|hw:1|256|2|44100|10|16|hwmon|hwmeter|soft-mode|32bit control device hw:1 configuring for 44100Hz, period = 256 frames, buffer = 2 periods ALSA: cannot set channel count to 10 for capture ALSA: cannot configure capture channel cannot load driver module alsa note: i have to set Gina24 to receive external clock from the ADAT box (its clock is 44.1k) in order to hear/capture the 8+8 digital channels. why jack doesn't see the new inputs? thanks in advance -- ciao Federico
