If you have a Windows 7 machine with a Realtek sound chipset or drivers, then you may have run into a problem where you randomly hear crackling or popping or static while playing audio through your speakers or even headsets.
I realized after doing some research that this is a pretty tricky problem to fix and it can be caused by all kinds of issues from latency to drivers to other hardware, etc, etc.
Step 2: Select the current playback device in use — by default it should be the speakers. Step 3: Go to Advanced section and change the bit rate to either of the following: 24bit/44100 Hz or 24bit/192000Hz depending on the speaker configuration.
If the issue is still unresolved, you can try another method for restoring sound: Step 1: Launch Start Menu, search for Device Manager and then launch it. Step 3: Right-click on the current sound driver and choose uninstall.
Don’t go to Dell’s site or try to update the driver from within Windows.

Hi, My Lenovo Model 2151 has no sound after an auto update of windows 8.1.
The bottom left hand corner of the screen shows an "x" on the sound icon.
Under this category, right-click on your sound card device name. With Professional version, you can update all drivers with just one click.
In Device Manager, expand category “Sound, video and game controllers“. With Free version, you are required to update the driver manually step by step.
