My Laptop lenovo  z51-70 has a sound problem as its internal speaker plays sound randomly like muting and unmuting .


Even if sound is playing suddenly no sound comes from internal speaker and,


Maybe after sometime the sound plays for 2-3 seconds and after that no sound.


It is  very random and i tried reinstalling drivers, updating drivers,


troubleshooting sound problems etc,


Although playing through external speaker is fine. any help in the matter will be appreciated..

It almost sounds like a loose connection on the internal speaker. Either at the speaker or at the sound card. It will take an educated look inside to determine if that is the problem.

The laptop connectors for headphones and power adapters really take a beating.  Most often they get jammed and the connectors mounted on the board get dis-lodged and become intermittent, even when not in use.
