Support for Midiman M-Audio Delta 410

Support for Midiman M-Audio Delta 410

[Kristof Pelckmans]

Hi all,

I bought a M-Audio Delta 410 card last weekend. When I tried loading the snd-
ice1712 module and unmuting all channels, I got a scrambled sound. (I did not 
try the envy24control since I have no X)

The last few days, I did some research and I found out in the sourcecode that 
the card is not fully supported.

Based on my pictures (see 
http://home.planetinternet.be/~kpelckma/delta410/delta410.html) I deduct that 
the Delta 410 has following chips :
- 1x AK4529VQ (A/D and D/A conversion) NOT SUPPORTED ?
- 1x CS8427 (tranceiver, I/O for AK4529 & S/PDIF), SUPPORTED also appears in 
Delta 1010LT and Delta Audiophile cards
- 1x ENVY24, SUPPORTED by ice1712
- 1x L7805CV (voltage regulator)
- 6x 5532 2036B JRC (operational amplifier, buffering & filtering)

In my opinion the real missing piece of code is the driver for the AK4529. Has 
any development been done to support this chipset ? For more technical 
information, see http://www.asahi-kasei.co.jp/akm/en/product/ak4529/ak4529.html.

If not, I am willing to write the code myself based on the work done by Anders 
Johansson for the Delta 1010LT. However I am not the best C-programmer, so 
therefore my cry for help and documentation ! Are there a doxygen generated 
docs for the kernel API ?

I am going to study the source code tomorrow and I'm hoping to write my first 
lines of code.

Best regards,

Kristof Pelckmans

the patch for ak4529 is already on my tree, but still lack of
information about GPIO bits for Delta410, so it's not functional at
all.
just waiting for answers from m-Audio.

Kristof, could you give us info to which GPIO pins of ICE1712 is the 
AK4529 chip connected?

Jaroslav,

Unfortunately I do not have the right equipment for measuring which GPIOs are 
used and what they are connected to. I assume there can't be that many used in 
comparison with the 1010LT. Probably very similar to the Audiophile's GPIOs...

Could I try it the old-fashioned way : simple try-and-error starting from the 
Audiophile configuration ?

Ciaos,

Kristof

Yes, you can. Simply, try to modify the alsa-kernel/ice1712/delta.c code. 
Perhaps, Takashi might commit the AK4529 support to have more fun...

ok, now it's on cvs.  please note it's not tested at all :)

I tried this over the weekend, but keeped getting core dumps. Next weekend, I 
will have the opportunity to give the exact GPIOs. Still upset that M-Audio 
writes that the card _is_ supported under Linux, while apparently getting the 
necessary info isn't all that easy...

Where is this stated? If M-Audio says that their newer hardware is
supported, I'll try to push my contacts at M-Audio to release
specification for newer products (like 410).
