Follow the instructions below ONLY if you are using the 32 bit version of Fedora 8.

First, you need to do is to update the repositories for fetching packages as they've changed. So, open an xterm and type the following commands:



su (provide the password for root)
yum remove pulseaudio*
yum remove yum
rm -fr /etc/yum.repos.d/*.*
rpm -ivh http://download.fedora.redhat.com/pub/fedora/linux/updates/8/i386.newkey/yum-3.2.20-5.fc8.noarch.rpm
rpm -ivh http://rpm.livna.org/livna-release.rpm
rpm -ivh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
rpm -ivh http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
rpm -ivh http://linuxdownload.adobe.com/adobe-release/adobe-release-i386-1.0-1.noarch.rpm


Second, now that you've updated the locations of where the repositories are and also updated yum you now need to update your entire system so in the xterm (still as root) do: --note this part will take a long time.



yum update
reboot


Third, since some media players don't strictly follow the Linux File Hierarchy standard in looking for a codec you need to create these directories and then install the media codecs to all of them. So in the xterm (still as root) do:



mkdir /usr/local/lib/codecs
mkdir /usr/local/lib/win32
mkdir /usr/lib/codecs
mkdir /usr/lib/win32
mkdir /root/install-temp
cd install-temp
wget -c http://www.mplayerhq.hu/MPlayer/releases/codecs/all-20071007.tar.bz2
tar -xvjf all-20071007.tar.bz2
cd
chown root:root /root/install-temp/all-20071007/*.*
chmod 644 /root/install-temp/all-20071007/*.*
cp /root/install-temp/all-20071007/*.* /usr/local/lib/codecs/
cp /root/install-temp/all-20071007/*.* /usr/local/lib/win32/
cp /root/install-temp/all-20071007/*.* /usr/lib/codecs/
mv /root/install-temp/all-20071007/*.* /usr/lib/win32/
rm -fr /root/install-temp/all-20071007


Fourth, now you need to install software packages (and their dependencies) that will allow you to play various media from a file or disc. So in the xterm (still as root) do:



yum install gstreamer gstreamer-plugins-base gstreamer-plugins-good gstreamer-plugins-python gstreamer-tools libdv-* libdvd* libdvb* realplayer rhythmbox vlc v4l2-tool v4l2ucp
reboot


Finally, you will need to check your sound settings throught the icon on your Gnome Panel. You should have no problem now.

I have found a few other posts regarding lost sound in Fedora 8. I have the same laptop and Fedora 9 had some scratchy sound occasionally (I never could figure out why), and Fedora 10 works perfectly.

Is there a specific reason you have to be using Fedora 8?
