Hi,
My goal is to become ridiculously involved in linux audio, mainly (at least for now) device driver development. I have an EZBus audio device/control surface/mixer, and an EZ8 ADAT I/O card (www.event1.com). My goal was to write an ALSA driver for the EZ8 card and EZbus for use with Ardour/JACK to do 8 track live recording and be a 100% open source band (we are currently using XP / Cubase). The snd-usb-audio works with the EZBus already, and how suprised I was to get sound out of the EZ8 card using the ice1712 driver. There is some noise there, and neither with alsamixer nor envy24control could I get any type of level control. Theres lots that need to be adapted to the EZ8 I think (channel assignments/levels, clock source, sample rate, etc), so thats what I would like to do as I learn device driver programming and linux audio. Right now I'm deep into the Oreilly Linux Device Drivers book, and browsing the ALSA developers docs.
So, here are my questions:
Is there a process for registering devices in the matrix and determining how 'functional' is enough to be considered 'supported'? Do I just shout loudly, 'EZBus works!' ? :)
If you could send an html addition to the appropriate manufacturer that would be helpful. Otherwise just these:
manufacturer, card name, chip, module name, needs midi firmware
Do any of the existing ice1712 developers have chip documentation I could have? Is it allowed / polite / acceptable for me to tear into the existing ice1712 code and learn from it, then either use code from it to create this driver or add complete EZ8 functionality to the existing driver?
Probably best to start with that and ask some questions as you go.
I assume this is the list to ask driver specific questions, which I'm sure I will have alot of as I dive into kernel land?
yes.
I read the home site asking for testers, I have alot of PC hardware at my disposal, do developers just post requests for people to test code as the need arises?
There are times when people need testing done. Just monitor this list.
Sorry about my generally 'clueless' disposition, but I guess I have to start somewhere :)
Welcome aboard.

Apparently upon the beginning of the barrage, the donkey broke discipline and panicked, toppling the cart. At that point, the rockets disconnected from the timer, leaving them strewn around the street. Tethered to the now toppled cart, the donkey was unable to escape before the arrival of U.S. troops.
