I've got serious problem with my sound from line-in input - I cant hear anything (when I plug a microphone, guitar or any music player). Strange thing is that I can record this sound, but I dont have any playback of it. I use Dell Studio 1555 laptop with Windows 7.
When I go to Control Panel->Sounds->Recording the sound is hearable for a few seconds and then stops again.
Its really annoying, but now my computer is really useless, especially if I need to record some music from external instument.
Did anyone have similar problem, and how to solve it?
