Do you have the correct sound driver, from Lenovo? Your System Specs only list "High Definition Audio Device" which suggests the generic, basic function, drivers that are installed by Windows. If this is the case, download and install the correct sound driver from Lenovo.

You did not list the Lenovo Model Number so I can't link you directly to the proper Lenovo driver.

Either there is heat causing the problem or some program that is not releasing the sound after it uses it. Those are the most likely causes.
