Description of problem:
I have a Dell CPi366 laptop.  When I install RedHat Beta (both Limbo and 
(NULL)) the sound does not work.  When I run the mixer it tells
me that I do not have permission to /dev/mixer.  When I change the permissions 
on the mixer, I still get the same error.

I also tried using 'aumix', but I get the same type of error (both as root and 
as a normal user).

When I use the sound card configuration tool, I see the following:

Vendor: Neomagic Corporation
Model: [MagicMedia 256AV Audio]
Module: nm256_audio

I press the "Play test sound" button and hear nothing.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Try to play sound :-)

Actual Results:  Nothing.  That's the problem.

Expected Results:  I expected sound.  Or some error indicating why sound could 
be produced.

I have this same problem with my sony Vaio Z505RX with both null and psyche.  I got sound again by using sndconfig as follows:

1)  start sndconfig as root
2)  went  through automatic configuration (doesn't play test sound)
3)  go through manual configuration (default values choose nm256_audio)
4)  system plays test sound and sound consistently works until reboot

i should also note that i could barely here the sound at first because my bios had the volume set low on boot.

Also running redhat-config-soundcard from a console instead of the menu gave me error messages about sox and /dev/dsp, i'll post the exact 
wording later

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
