Thanks for your testing.

The mode switch for digital input interface between S/PDIF and ADAT is 
on 0xffffe000011c of device registers. When it's 0x00, ADAT is enabled. 
Else, S/PDIF is enabled.

Currently there's no plan for the driver to have control elements for 
this, because it's can be implemented in userspace. For this purpose, 
please develop your own application or use 'linux-firewire-utils', like.

./firewire-request /dev/fw1 write 0xffffe000011c 0x00000001 (S/PDIF)
./firewire-request /dev/fw1 write 0xffffe000011c 0x00000000 (ADAT)

By the way, now, the driver is drastically changed (and rename to 
snd-firewire-digi00x). If you have a rest of time, please test the 
current version under 'amdtp-variants' branch.
