Supporting Ego Sys (Esi) WaveTerminal 192L

[Mathias Friman]

Hello list.

I have a friend that has got a Esi Waveterminal 192L, which
by the Alsa sound card matrix seems unsupported as of now.

Is there some way that we can assist for someone to develop
a driver for this card, and what information would you need in
that case? 

I'm not a C-developer myself, so I don't see that I can help
in any way but passing information. :(

Regards,
Mathias

We would first need a hardware sample.
We would then need a datasheet from the manufacturer.
Without a datasheet, reverse engineering is required that takes a long 
time normally.

The board has likely VT172x controller chip.
This board is flexible to be configured with different codec chips and
protocols.  So, you'd need

- which VT172x chip is used
- which codec chips are equipped on your board
- how these chips are connected with VT172x chip (pin to pin)
- which protocol is used for communication between chips
  (AC97, I2S, I2C, SPI, etc)
- I2C address, special GPIO pins, or any additional requirement

The last two are often not too easy because it's a guess work if you
have no information from the manufacturer.  You should contact with
the h/w manufacturer, and take a look at the source code around
pci/ice1712/ directory.
