Current implementation of snd-firewire-lib can handle only AMDTP transmit stream with PCM. This series of patch enable it to handle both AMDTP receive and transmit stream with PCM according to IEC 61883-6.
I develop with Echo Audio's Fireworks (AudioFirePre8). Unfortunately it's not fully compliant to IEC 61883-6. The last patch includes some work arounds for Fireworks. The snd-fireworks is still under development and not prepared for commit.
And this commit includes some variables and functions which are currently useless. They are for future MIDI implementation referring MMA/AMEI RP-027.
