This is very important information. How about explaining this on the
alsa-project.org website where the current sentence reads "simply copy ..." ?

I probably want the new/experimental drivers.
  cd alsa-driver-cvs-20040302
  ./configure --with-cards=.... --with-kernel=somewhere/linux-2.6.x
Does this mean the both ALSA and OSS sound modules in the Linux 2.6.x source
tree are automatically replaced and updated by the ALSA and OSS modules
from alsa-driver?  I want to have the old OSS sound drivers so
I can change from using ALSA to OSS (and vice-versa) by modules unloading
and re-loading.

Ok, so is this a correct summary of installing alsa-kernel into Linux 2.6.x?

#!/bin/sh
# Install CVS alsa-kernel into Linux 2.6.x source tree:
    cp -fR alsa-kernel/include/*  linux/include/sound
    mv -f alsa-kernel/include  out-of-the-way-temporarily-include

    cp -fR alsa-kernel/Documentation/*  linux/Documentation/sound/alsa
    mv -f alsa-kernel/Documentation out-of-the-way-temporarily-Documentation

    mv -f alsa-kernel/oss out-of-the-way-temporarily-oss

    mv -f alsa-kernel/scripts out-of-the-way-temporarily-scripts

    cp -fR alsa-kernel/*  linux/sound

Thanks,

William
