Hi,
as the owner of a firewire audio card (Motu 828mkII) I was disappointed when
trying to use it under linux. Asking Motu to provide tech docs and/or linux
drivers is useless: "We will possibly release linux drivers in the future,
but we never release any kind of technical documentation."
Is there any effort to join forces for putting pressure on the manufacturers
yet? I am willing to create an address list ordered by audio card
manufacturer/model to make the manufacturers realize there is a need for
linux support.
Any comments?

That is actually a big improvemnt. When we (linuaudio.org) were demoing at
Sounds Live in London earlier this year, the were telling thier users that
they had no intention of supporting linux, and wouldn't release docs.
Though with the number of thier users we were sending to them to ask, I
guess they were getting a bit concerned :)

Short answer: IP! (Intellectual Propererty!) Combine that with PHB
(Pointy Haired Boss), and you can't tell anything obvious without
loosing your job.

Mmmm ... I could do the opcodes allright. I'd hate to do the soldering
though(, and forget about producing that layered card.)

Yup, more specifically, "our competitors will rip off our hardware
design". This is why vendors will often give out hardware, and even
help driver writers once they have it working. They just want to keep
the learning curve steep for someone who just grabs it off the shalf.
That being said, sound cards are not rocket science (or more aptly they
are not GPUs). Use a DSP with a documented instruction set and wire it
to ADC & DAC.

You supply gerber files and major components. They supply standard
passives at no cost.
Price? Less than 500 UKP, ie less than 50 UKP per board.
The objective, IMO, would NOT be to produce a finished, fully engineered
end-product which users could build for themselves. It would be to produce
a reference design with open firmware, open protocol and open drivers.
Given such a design, companies (possibly very small ones at first) could
produce and market finished hardware. This might be very similar to the
reference design or it might not be, but it would be compatible with it.
They would still be able to differentiate their products by audio quality,
number and types of inputs, packaging and price etc.

That is exactly what I'm talking about;)
Also, look at other libre hardware
the leon cpu
the manticore gpu
