Hello Folks,

I have installed Fedora core 8 on Acer Aspire 5720Z and the sound was not working .

I tried to solve the issue and in doing so have messed up with too many of sound components , including downloading latest ALSA and building it and i don't even remember what else. All to no benefit .

Later i came to know that all i had to do to make sound work was to put a file named alsa-base containing the line : "options snd-hda-intel model=acer index=0" in /etc/modprobe.d and restart the laptop.

A friend of mine with same laptop and Fc8 tried this and his sound started working . But for me now , that too does not work . This i suspect is because i have manually messed up with a lot of sound components.

What i want to know is how to get Fedora 8 sound components on my laptop to the exact state that comes with Fc8 installation , so that i can get my sound working? Something like a repair option that only brings Fc8 components at par with installation , but does not mess with my data on hard drive.

any help is much appreciated.

Thanks in advance.

Taha

Try a yum grouperase "Sound and Video" followed by a yum install alsa.

If you'd like something less potentially catastrophic, I'd suggest a yum grouplist "Sound and Video" first, and then for each sound component whth which you've messed, a yum erase <component>. Pay close attention to the dependent packages that will be erased if you proceed, and, if the list includes undesirable things, download the rpm for that package, and do a rpm -F <package-you-downloaded> to"freshen" the package.

Also, remove any configuration files with which you've messed and let the new install create the default versions.

For anything you've installed from source, try a make uninstall. Some (but not all) developers include that (or something similar -- try a make --help to see what's offered) as an option.

Alternatively, just restore your system from the last backup you created before you started messing.

Thanks for your message PTrenholme.

I could not get the sound to work through any method , so i did
a fresh install and added the file i mentioned in original post . And bingo , my sound works now

I struggled with Fedora 8 sound problems for a while but this is what works for me - I am running KDE 3.5

yum groupinstall sound-and-video kde-desktop

This installs some specific files that work with KDE.

After this I had sound, but the volume was very low.

alsamixer -c 0

The number can be 0-7, keep trying until you find your card.

alsamixer has a weird input method using page up, page down, arrow keys etc. Play with it until you figure how to set each control to maximum.

Now you should have sound.

I think the key is to use the specific sound-and-video packages for KDE.

I think there is also a yum groupinstall sound-and-video gnome-desktop for gnome users.
