Hopefully the # at the end of the above line is not really there.

As far as I can see it should work, but Iīve disabled the Joystick
(snd_jport=-1) and the
FM synth (snd_mpu_port=-1, not required snd_mpu_irq).

Use amixer (or xamixer as I suggest on my pages) and make sure that all of
the required
audio levels are set as required, and that the channels are not muted. I
actually had
ALSA working for a whole day without any sound because I forgot to unmute the

channels.

If you are sure that this is all OK then try aplay against an .au or similar
audio file
and see what happens. The biggest problem with ALSA is that various progs
require
a "--with-alsa" when you call ./configure to enable their (if any) ALSA
support.

When everything is as you want it the issue the "alsactl store" to save the
current
audio setting into /etc/asound.conf.

Oh another thing you could try:
    1. remove the "alias sound snd-card-0" entry (Donīt just comment it out:
see /etc/rc.d/rc.sysinit)
    2. change the alias sound-s* entries to snd-s*
        [ RH looks for "alias sound" in conf.modules. (Better would be "alias
sound " note the trailing blank ) ]
    3. add the following two lines to /etc/rc.d/rc.local:
        modprobe snd-card-0
        alsactl restore

I do it this way because ALSA didnīt seem to be initalizing correctly when
being started from
/etc/rc.d/rc.sysinit.
