Maybe your line-out is muted? Supposing you use Alsa, try entering "alsamixer" at the console. If the volume bar of the Master channel is empty, push it up to, say, 75 (might have to press M first to un-mute it), exit the program and enter "alsactl store".

Of course, the problem might be an entirely different one, but I think it's worth a try.

i configure Volume Control in graphic mode.It is suddently OK .I don't know why.But it works well now.
Maybe i had forgotten to save changes made before.Also thanks for your help.

For the benefit of others who had this problem, you need to enable "External Amplifier" in the mixer.

Thank you very much!!!!
i just found my HP v3172 laptop can't hear any WITH a earphone.
Maybe i forget to enable the External Amplifier.

In the graphic mode or alsamixer??
