interfacing with ISA or PCI soundcards

Hi
Please,i would like to read something about controlling a soundcard with a
microcontroller or FPGA,but i'm not able to find any link about,can you help
me?
thanks
Diego

Why don't you simply interface a codec to your MCU/FPGA?

The fact is that i have some old soundcard aavilable,and it looks difficult
to find the datasheet of the Ic's mounted on these boards,another reason is
that a complete card  has the ic mounted,with supplies,decoupling
capacitor,look easier to do
but it would be possible to use the codec,if if you can suggest me the
link,the one i have mounts crystal,creative,yamaha ic's

I forgot to say thanks

The Si3000 is very easy to use, but only suitable for speech. I've
used with a dsPIC.

Running ISA cars from an an FPGA or micro implementing/emulating that
bus interface is a reasonable project.   Running PCI ones generally is
not, unless the device you want to use has real PCI (master) interface
capability (which is not unheard of, but it is more expensive.  Also
you'd have to be more careful of signal integrity).

To pursue the ISA path you will need some background information on
the workings of the ISA bus and a programmers manual (or well
documented driver source code) for the board you are interested in.

While you comment about power supplies and the like being provided is
valid, do keep in mind that an ISA card is going to present a parallel
interface (and probably be an ancient codec IC) while a modern codec
IC will have a serial interface that means far fewer wires going to
your fpga board.

Thanks for your help , cs_posting and Paul .
