Is there a Crystal 4299 sound driver?

Is there a Crystal 4299 sound driver?

[Torrey Hoffman]

Does anyone know of a driver for the Crystal 4299 sound chip?

I grepped through /drivers/sound in both 2.2.18 and 2.4.0. 

The only hints were that "ac97_codec.c" has two codec id's listed for it.
>From old changelogs I see that Mulder Tjeerd was involved in adding those...
perhaps he is writing a driver?  

Any hints would be appreciated.

It's not something there's one particular sound driver for (it's just
an ac97 codec chip, as you saw). Most likely you want to use something
like the i810_audio or via82cxxx_audio drivers. What does lspci say
on your machine?

Here's an lspci -v dump.  The machine is a set top box, pretty much a
standard PC, but with hardware parts that are rarely seen in normal 
desktops.  (The graphics card, ethernet card, and MPEG decoder chip
all required non-standard Linux and X 4.0.2 drivers to work.)

Use the i810_audio driver; either 2.2.18 or 2.4.0 should be more or
less OK.
