[FFADO-devel] DiceDriver version

[Uli F. <uli...@we...>]

Hi Brian, Hi Pieter

Whilst trying to get one of our devices running I stumbled upon the DiceDriver
version. ffado uses the 1.0.7.0 specification which seems to be much newer than
the latest revision in the TC SDK what leads to horrible register address
offsets. What's that 1.0.7.0? How it comes that ffado is even more recent than
the official sdk? And which vendor uses this version? There must be focusrite at
least, probably alesis as well, since there were some reports of working
devices. What about the 1.0.4.0?

Anyway: Somehow ffado must be able to differentiate between those both (or later
probably more) versions or at least die with an error if the currently compiled
 binary isn't compatible with the firmware. The latter would be easy to
implement. I'm simply afraid that uncommenting the 1.0.4.0 version define and
commenting out the other simply reveals some other problems, I already tried it
and got a wrong number of RX channels (0). Perhaps the transition to 1.0.7.0
limited the compatibility with 1.0.4.0? Could you comment on that, Pieter? Did
you observe something?

Any suggestions from either party where to go? Is 1.0.4.0 deprecated anyway?

Regards
Uli
