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..
