Im on it! I will throw the questions out to the board and regular progress - hopefully I can get through this pretty quick

Older and newer isn't an issue at all it seems, as they're virtually identical from the driver POV. All cards are 24 bit internally, and the DMA subsystem seems to scale to 100 kHz without too weird hacks. We can support any model, so let's just start with the ones we have (Layla20, Darla20, Gina20, Darla24), and maybe throw the firmware for the others in later, so others can test directly.

Ok, you got the job! ;-D > I just need some more > detailed chip specs and a little time - There is no detailed chip spec, but OTOH, drivers talk mostly to the firmware it seems. There is some documentation in the C++ driver archive, but it's mostly higher level stuff, dealing with the API of the C++ driver rather than talking directly to the cards. The idea is that you should plug your platform specific stuff into their C++ driver and use that, rather than implement a new driver. So, the "documentation" we have is the driver code, which is the very code that runs these cards on the currently supported platforms. Maybe not optimal, but at least it's the *real* code, and not some incomplete and half broken "Linux port". //David Olofson - Programmer, Composer, Open Source Advocate .- The Return of Audiality! --------------------------------. | Free/Open Source Audio Engine for use in Games or Studio. | | RT and off-line synth.
