I was having trouble getting onboard sound to work in three computers- HP 
Pavilion, IBM Netvista, and now an SiS-based ECS board.  They all use 
Intel 810 sound in an integrated sound/video/etc chip on the board.
I compiled my own kernel and modules for 2.4.31 to support this 
sound after the modules for 2.2.26 would not insert:

http://keesan.freeshell.org/html/bl/2.4.31/bzimasmz.431
http://keesan.freeshell.org/html/bl/2.4.31/configsmz.431
http://keesan.freeshell.org/html/bl/2.4.31/modules-smz-431.tgz

I have a few other kernels there - one 'la' for a laptop without scsi, 
sound, framebuffer, or ide zip, one similarly minimal kernel 'pd' for use 
only with USB pdas, because there is some bug that prevents you from 
inserting usb_serial in 2.4.31 so it needed to be compiled into the 
kernel.  (It works in 2.2.26 as a module).

I can try to add support for any other requested sound, etc.

Also i810_audio.o posted separately, which inserted in my previous kernel 
bzimasm.431 or in this new kernel.

insmod soundcore   [do not need sound.o]
insmod ac97_codec 
insmod i810_audio.o

I compiled by answering 'm' to a section about Intel ICH for 8xx chips. 
This sound is part of i810 integrated audio/video etc. chip on our HP 
Pavilion, our IBM Netvista, and now an SiS board.

I also added support (modular) for aic79xx (onboard scsi controller on our
dual-cpu Tyan), and built-in support for IDE zip driver.  s - scsi and 
sound, m - modular (as opposed to an sy kernel with scsi built-in for use 
with linux on a scsi drive), z for zip. Supports vesafb, matroxfb, and 
others.  A previous sm2 kernel broke matrox so I deleted it.  The same 
modules should work with all my 2.4.31 kernels but not David's, which he 
compiled using a different glibc.  See files with 'usb' in them for his 
kernel and modules.

pcmcia modules are in a separate package, as are a small set of non-pcmcia 
modules for use with the laptop kernel.  (I have not used sound with our 
laptops yet, or framebuffer, and needed a smaller kernel for low-RAM, and 
don't need ISA support...)

David Moberg:

With the new kernel I can now play sound with mplayer (mp3, ogg, wav) or 
timidity.  I could not insert opl3 to use playmidi, no such device.

But:
play:  sox:  Unable to set the sample size to 8.
mpg123:  No supported rate found.

Does this mean the sound chip is not suitable for use with these programs, 
or I would need to tweak the programs?

The chip is relatively loud, compared to my PCI cards essolo1, es1370, 
es1371 (a bit louder than the others) and sblive.  It might even be usable 
with some low-power powered speakers that were hopeless with solo1.

Would someone else with this onboard sound chip please try to get it 
working with kernel 2.2.26 or 2.2.16?  Or would anyone at all try to 
insert ac97_codec.o, needed by i810_audio.o, which inserts in 2.4.31 
whether or not the chip is there?

No, it appears to be some other problem.  I could insert i810_audio in 
2.4.31 kernel that was not compiled for it.  2.2.X does not seem t work 
right with i810_audio.o

Intel ICH worked, for i8xx and other intel integrated chips.
