jack, layla, and adat

i’ve been using ardour with a layla 3g and everything’s been great. however i have a session coming up that will require more than 8 simultaneous channels. i have an alesis ai3, which is a simple a/d adat interface, connected to layla’s adat in. when i open the layla mixer and enable the adat in, i see all 16 channels light up with analog noise. however, qjackctl and ardour only show 8 inputs. any ideas what might cause this? is there a way to manually override the channel count? the “input channels” option doesn’t seem to work.

figured it out. the echo driver presents the analog and digital i/o as seperate pcm devices, so i made an .asoundrc to combine them. works great now!
