Hello.

Is there a way to open jackd with all 26 ins and 26 outs on M-AUDIO ProFire 2626 with alsa backend? aplay see 2 devices, but I can use either one or another at a time. One have 10 inputs and 10 outputs, another have 16 inputs 16 outputs. So the driver knows about all I/O. Can they be used at same time?

I have tried to specify io channels counts but jack wont start.

Main problem for me is to use 3 snd-dice devices together interconnected via ADAT but actually record and playback only one of them. I still need them connected to firewire bus to control internal mixers for direct monitoring. FFADO is always opening devices in daisy-chain mode showing all ports. This is causing sync issues and unstable playback. PipeWire show all devices, but as separate nodes and its adding a huge 90ms delay with ALSA backend. And I believe it performs some adaptive resampling on the fly. So for now the only option I have is a second laptop with ffado driver, it's working just fine when connected alone. But it's a bit inconvenient.
