Check that your system volume is not muted or set too low

To adjust your system volume levels, access the speaker icon on your computer's taskbar. If you do not see the speaker icon on your taskbar, see your Windows Help to learn how to access it.

Update your sound card drivers

We recommend that you update your sound card drivers on a regular basis. Visit your sound card manufacturer's website to verify that you are using the latest drivers.
