Welcome to the forums!

Can you tell us what sound device you are using?

Also, check to be sure that volume isn't muted because it often is, by default.

Go to the audio mixer and check the PCM level. It is often off (0) by default, resulting in no audio output. Move it to the highest setting, and adjust your volume with the master volume control.

Also, you should be using the ALSA sound system and drivers.

im using ALSA driver. your idea is confuse. i cant find audio mixer in fedora 10. i know that the older version of fedora has the software to detect audio card. but im using version 10. it have one way to set audio by visualization tool:
Preference --> Hardware --> Sound and set somthing here.
i set every thing and click test but i hear no sound, both front and back.
some friend tell me if i want to write c++ program, i must use linux. i used linux some day ago and i find i realy well. but the bit happiness when i use linux is music does no work. my friends have sent me some advises, and i also look for on internet, but i not find good solution to solve my problem.

Are you running the KDE or Gnome desktop environment? If running KDE, then open a command-line window and enter the command: kmix
That is the KDE audio mixer UI. In the Output section, you should see sliders for Master, PCM, Front, Line, CD, Mic, and Digital. Set the sliders for PCM and Front to the top (highest value) and Master somewhere about 1/2 way. I usually set CD to the top as well, though I never have found that it affects anything.

If when you start kmix you only see an icon on your shortcut panel, then click on that, and then on the Mixer button at the bottom of the volume slide.

i use gnome. i see your solution but my sound does not mute. some guy in the fedora forum tell me write command : alsaunmute. and the result:
Unknown hardware: "HDA-Intel" "Realtek ALC880" "HDA:10ec0880" "0x1043" "0x81a7"
Hardware is initialized using a guess method
i dont know what it mean??. why it is initialized by a guess mode and why linux doesn't fix this problem to make life easy?
and at last i guess that this driver does not support my sound card . it to bad . so i have installed two OS on my PC, windows xp to listen music and fedora to work . i think it is good idea
