no sound after installing fedora 7

installed all the codecs for video and audio using yum.

was able to play avi movies but no sound.
all the mp3 sound codecs were updated but still no luck.

please help me i am a newbie to linux

That looks like sound card issue. I suggest that you post the output of the following:

lspci | grep sound

and

lsmod

Also check the speaker icon (top right if you are using Gnome) to verify that the sound isn't muted; you should also right-click and select Open Volume Control to verify that you are using the correct sound card if you have more than one.

By the way, Anaconda (the installer) runs a sound test as one of its last steps. Did you get any sound or not?

hi jay , have attached the outputs of the commands that u asked for, please help me out

also while installing i did not get any sound.
checked the right click option in the volume control , it shows 2 devices one is the alsa mixer and the other one is the OSS mixer. i use alsa mixer.

Oops, sorry, that should have been

lspci | grep audio.

Can you redo that one?

no output
 

i didnt get any output from the command :

lspci | grep audio

That's not very good knows, it seems it can't even detect your sound card. If that is correct, there is nothing you can do. Do you know by heart which sound card you have?

sound card
 

i think it is detecting my sound card.
when i go to the system and administration menu in the desktop i see the following sound card selected.

selected card

Vendor : ATI Technologies
model : SB450 HDA audio
module : snd-hda-intel

tried doing many things by googling about it.

still not working.

Sound
 

I had a similar problem. I solved it by doing:

That fixed it for me, but I'm not sure how helpful it will be to you.

Good luck!

Ouch, the ATI SB. I remember assisting others with the same issue and I'm afraid that we never found a way to get it to work. Yes, you're right, there is some information on the net but little or none of it actually helps.

getting sound now
