[nwst-dev] Audio on the NS1000

Hi!

I'm trying to work out how to make this thing work, we have a CS4231A-KQ.

The first problem would be which driver to use for this chip, the thing is
that searching at google, this chip doesn't seem to be alone on a card, the
cards usually have a DSP or some other things as for the CS4231 seems just
to be a codec :-? Depending on the card you need one driver or another, so I
really don't know which one to use.

Jochen sugests to use the CS4232 driver, but you can read on it:

 * The low level driver for Crystal CS4232 based cards. The CS4232 is
 * a PnP compatible chip which contains a CS4231A codec, SB emulation,
 * a MPU401 compatible MIDI port, joystick and synthesizer and IDE CD-ROM 
 * interfaces. This is just a temporary driver until full PnP support
 * gets implemented. Just the WSS codec, FM synth and the MIDI ports are
 * supported. Other interfaces are left uninitialized.

So, the CS4232 seems to be a chip that has a CS4231A inside, ok, maybe this
one works, it seems to be the best one at least looking on the kernel, don't
know for ALSA. I know it compiles, that's a good start ;-)

Now, the second problem is that this driver needs the IO, IRQ and DMA for
the card, and I don't know how or where to get this info from, so...
is there anybody that may guess this? maybe one can use NetBSD for getting
this values? (Berto, you have that BSD thing running there, can you try to
find this values?)

Well, hope you can help a bit with this, as for me, having sound and 16 bpp
are the things we are missing the most.

Regards!
