I have asked the DAL people how we could get a Linux driver and they 
replied that they've already had NDAs with a couple people to build a 
Linux driver to no success.  They said they had to explain basic 
concepts to them and it wasted too much of their time.  They are 
reluctant to provide me with details as well because of this.

Secondly, they desire to release a BSD-driver, not a GPL driver as a 
condition of an NDA.  I personally just wanted to make an ALSA driver, 
but ALSA is GPL'd, which creates a problem.

I have no driver writing experience personally and am really quite busy 
to learn everything to write it myself.  I'm wondering if anybody on 
this list has already talked to DAL about it and if so, why there was no 
success.  Depending on what has already happened, I might drop some 
secondary projects to add time to work on this directly myself, but I 
want to know if it's worth it.

It's the only hardware I own that doesn't work on Linux or any other 
free OS yet, and I would like to use it in Linux because the sound 
quality is literally unparalleled to any other card out there that I 
know of.

Does anybody have any information, advice, suggestions on what I could 
do to facilitate the process of getting a Linux driver for the 
CardDeluxe?  Their website is at http://www.digitalaudio.com for the 
interested.

If someone donates a sound card to me, I could probably write a driver.
I have done so for some of the Creative Sound cards. They would
certainly not need to explain basic concepts to me. I would only need a
half decent datasheet.
The NDA should not restrict the license I wish to place on the driver.
If I write the driver, I choose the license.
DAL specifing the license sounds to me like FUD from DAL. I don't
believe for a second that they have signed any NDAs in order to aid open
source driver development.
One other thing I would need is external devices it might plug into. I
obviously have speakers and spdif devices, but I don't have MIDI or AES
8-channel devices.
