This is probably a driver issue. You can test this by connecting headphones to the laptop and listen if you get the same audio problem. If you do then the best way to update the drivers is to go to Lenovo - Support and download the current driver. If the head phones do not have the same problem then it probably is the built in speakers, you can get information on part numbers at the same Lenovo -Support site.
