Hi Mark. First of all, apologies for harping on about pulseaudio, but it does 
seem to be causing problems for some folks. According to synaptic, pulseaudio 
is a replacement for Gnomes ESD. Now I don't use Gnome, but KDE. The only 
package I had to remove was alsa-plugins-pulseaudio, which also removed 
kde-settings-pulseaudio, and this effectively disabled pulseaudio. I did not 
remove any of the other packages named "pulseaudio".

Someone else on the list merrily went ahead removing pulseaudio packages, 
including pulseaudio-libs (which removed vlc (which he wanted to keep)), and 
totally screwed up his F8 install. I'd already told him that he only needed 
to remove alsa-plugins-pulseaudio, but after reinstalling F8, he again went 
ahead, admittadly more carefully this time, but removing the pulseaudio 
packages all the same (excepting pulseaudio-libs). Then he looked back over 
previous posts, and saw that the only package that needs to be removed was 
the alsa-plugins-pulseaudio one. IIRC he was using Gnome too.

Now I know absolutely nothing about pulseaudio, apart from how to disable it, 
but just wonder, and as you are using Gnome, perhaps you should replace the 
pulseaudio packages that you have removed, that is apart from 
alsa-plugins-pulseaudio that enables pulseaudio. It's possible that Gnome 
relies on some of these pulseaudio packages to have sound working through 
Alsa, even though pulseaudio is disabled by the removal of the 
alsa-plugins-pulseaudio package. Just guessing here.

If you want a list of the pulseaudio packages installed as per a fresh install 
of F8, just ask.

Moving on from pulseaudio to alsamixer.

>From one of your previous posts you have no alsamixer on the command line, as 
below.
alsamixer:
     [mcallman at prez tmp]$ alsamixer

     alsamixer: function snd_ctl_open failed for default: No such
     file or directory
 -- Mark C. Allman

Do you have a file named /etc/alsa/asound.state? This file is used when you 
bootup. ? /usr/sbin/alsactrl restore is run and restores the mixer settings 
that were saved when you last shutdown. Running alsamixer on the command line 
should bring up alsamixer playback settings.

Do you have the package alsa-utils installed? It should have been installed as 
part of the F8 install, and includes alsamixer, and a bunch of other stuff.

Regarding /etc/asound.conf. I don't have that file on my F8 install, but 
didn't have to run system-config-soundcard to get my sound working, and from 
a bit of googling found this entry.
http://pastebin.ca/45042?srch=asound

The first commented out line says the file is created by 
system-config-soundcard, but as I've never had to use that command, it's 
probably not surprising that I have no /etc/asound.conf.

Moving on now to your /etc/modprobe.conf, and the options for your soundcard.

The guy I've posted to, and is using the same machine as you, but is using 
Suse, rather than Fedora. Anyway, this is what he has to say.

Hi Nigel,

After a quick glance I'm pretty sure your user is kind of semi clever.

I'd bet he had used a Toshiba notebook before and blindly copied some
of that config info over to his Dell.

In particular he uses some utterly stupid modprobe options when loading
his alsa driver. From his alsa-info output:

!!Modprobe options (Sound related)
!!--------------------------------

snd-card-0: index=0
snd-hda-intel: index=0 model=toshiba
snd-usb-audio: index=7


!!Loaded sound module options
!!--------------------------

!!Module: snd_hda_intel
enable : N
id : <NULL>
index : 0
model : toshiba
position_fix : 0
power_save : 0
power_save_controller : Y
probe_mask : -1
single_cmd : N



Just instruct him to remove at least 'model=toshiba' if not all modprobe
options alltogether. I'd bet then his sound will work.

Bbest,
Michael


Now what Michael says is based on that he has sounds working on the the same 
machine as you, but using a Suse distro.

I'm still trying to provide help to resolve your problem, and nobody else is 
coming in. Be that as it may, it would be nice to resolve your problem.

All the best.

Nigel.
