Hello All
I've just installed fedora 15 to try out Gnome 3and came to know the sound is not working . I've tried changing the setting from "Sound Setting" but didn't work. lsmod gave this

[vinodh@Joshua ~]$ lsmod |grep snd

So this indicate that the driver is installed ,but i can hardly hear anything . I even tried installing "pavucontrol" but its of no use. As a last try ive tried installing sound drivers from Reltek website but ive got error while configuring. Please help me resolve this . Sound is important to me as of now

Thank In Advance

Hi!
First I would try:
Terminal:
Hit F6, choose sound card and adjust channels.
alfredo

Thank you for that reply alfredo. Ive already done that from the terminal . I could hear nothing .

Hi!
There is another possibility: (I know what you wrote)
You ' ll get an error message, but a window will open - maybe you must "unlock" channels together
(one to 80 - 90%, the other to 0%) - it's the button in the middle.
alfredo

The ONLY option in systemsettings for sound is Pulseaudio

you gotta un-muted the "hardware" also look at "internal playback" and too..
make sure everything is unmuted... you got that? brother vinod?
