my winamp doesn't play songs
 

there's no sound when i'm playing all my songs in winamp
none of the songs work
It is working everything, but just haven't any sound

Lets start with the common but easily missed problems…
Check the Winamp volume
Check the pre-amp volume in Winamp's equalizer.

Double click on the little speaker icon in the tasktray (systray) and make sure the Various volumes are set at a good level or uncheck any of the mutes.

Check the output plug-in…
Winamp > Ctrl+P (for preferences) > Plug-ins > Output > select DirectSound (for WinXP or Win2000) or waveOut (for Win 9x, ME or NT4)

Still no luck?…
Please post a reply with answers to the following questions…

What file types are you experiencing troubles with? (MIDI, WAV, MP3, OGG, MOD and so on)
Windows Version?
DirectX version? (Start button > Run... > type DXDIAG > click OK > System tag)
Soundcard?
Did you have any third party Winamp plug-ins (add-ons)?
