With the newer kernels, you don't need to do anything outside the kernel
for Alsa sound most of the time.  Make sure to configure the kernel so
that it has basic sound support enabled (I would compile this into the
kernel, not as a module, but that is me).

Next, on the menu where you choose options, leave OSS unmarked, and
select Alsa support.

On the submenu for Alsa support, select everything that applies (Do
select OSS Emulation, as some packages don't ASK which driver you are
using, they just assume the one they want is there).

If you select extra things here, it won't matter much.  The extra items
are just Midi drivers, and if you don't have Midi hardware, they aren't
an issue either way. ^_^

In other words, on this screen it is safe to select pretty much
everything.

On the screen for PCI drivers, select the option(s) appropriate for your
hardware.

'lspci' should show which sound card your system has.

If you are using devfs, then the device nodes should be created
automatically, if not then I am not sure how to create them manually in
an old style system.  It is possible, that you may need to manually
chmod a+wr the device node in order use them (This is assuming they are
there, which you said they were not I think).

Also dsp, should be /dev/dsp in many cases.  Many of the items you want
will be under /dev directly instead of /dev/sound  These may be links to
the /dev/sound items, but I am not sure. ^^;;  More experienced people
can probably tell you that.
