My headphone is not working in widows7,but in windows xp its working.Is my computer works on 1GB ram on windows,its all are working in windows 7 but only hesdphones are not working in windows 7.. please tell me what's the problem for not working my head phones in windows 7.

Did you set it as the default playback device? Right click on the sound icon in the bottom right of your taskbar (next to where the clock is) and click on playback devices (not recording devices). You should see 1 or more devices, please tell us the names and we can figure out what you have to set as the default device.

Or just simply fix the problem by elimination - set each device as default, one by one and see if the headphones work by playing some music or something.
