your sound card drivers are transforming into corrupted, you will ought to reinstell them, you ought to have have been given a disc with the laptop called drivers and utilities or comparable, insert this and set up the drivers or bypass to the manufacturers information superhighway website and get them there under downloads
Try reversing the polarity of the speaker wires. If that doesn't change anything buy new speakers. There may be a problem on the volume control in the speakers themselves.
The speaker is play music using the power output from your mp3 player, when external power is connected it is amplified at Least this is what I think, would help to know a bit more about the kind of speakers. So sounds to me that your external power isn't reaching the speakers, could be anything from faulty wiring to a crack in a circuit board. Sorry I couldn't be more help and hope you work it out
