But I cannot hear all of channels which I send. My AudioFirePre8 can playback 16ch (differed in current sampling rate). When I playback 16ch with aplay or jackd, I can hear only 1/2ch physical output... I hope you to confirm this on your devices. Currently my driver fully utilize ALSA's snd-firewire-lib.ko to transmitting (and receiving) stream. But snd-firewire-lib.ko has no codes for receiving (=PCM capturing). I'm under working for this.
