Sound problem: i've search everywhere, a lot have this problem but nobody solved it

[meeshoo]

Hi. I've installed fedora core 4 (i had fc3 before). in fc3, my nvidia onboard soundstorm device was woriking fine. Now, during instalation, i've clicked the Test Sound on sound card detection step, and the sound was fine. I've got sound in gnome, then switched to KDE , rebooted and got sound there too. After running some yum updates, when i'm rebooting i got the sam message, that says it cannot initialize the sound device and will use null device. (there are a lot of topics on the forum and google about it, but nobody knows how to solve it). I go to sound card detection, and there it says about nvidia soundcard, but when i press test sound i hear nothing. i don't know what to do anymore. Plese help.

Well I experienced the same problem yesterday, but I have a Sound blaster not onBoard sound. So i went to the audiocard detec and they ask me if I heard the sound... first time I awnser no... but then I ran the test again... awnsering yes, I reboot the system and TADAM I now have sound... It's a totally random thought, but maybe the yum updates writes the xorg.conf file and you need to redetec... anyway I worked for me... hope you problem is nothing more then what I had

Hello guys, I also have a problem with sound. I installed Fedora 4 on my Dell Inspiron 5100 and so far the only thing that is not working is the sound. The sound is listed as snd-intel AC97 but it does not matter what I try it does not work at all. Has anybody experience the same situation on a Dell laptop. Any help will be greatly appreciated. thanks.

just to check a forgotten trivial ..
maybe u guys can try checking the alsamixer settings once ?? maybe the volume is low/muted ??

What if you KNOW that you have a soundcard but Fedora refuses to detect it?
