Check the volume and mute settings
If sound is not audible, it is possible that the sound control is turned down or set to mute. There are separate sound controls for the hardware devices (speakers / head sets) and the individual applications (Windows sound / QuickPlay / Windows Media Player). For example, if the speaker is turned on, but the application is muted, you will not hear any sound. You should open the sound volume mixer and check the different settings.
NOTE: If the volume for an application, such as Windows Media Player, was adjusted using the volume buttons or slider controls on the notebook case, the system will use that volume setting, even if the master volume control is adjusted to a higher setting.
To check the volume and mute settings, follow the steps below.
- Double-click the sound icon
in the task bar, and then select Mixer . All of the active sound applications display.

and sound
.
NOTE: Because each sound device has its own mixer control, click the icon
to enable sound for muted devices.
- Drag the slider bars to the highest volume settings, and then test the sound again.
The sound should now be restored. Adjust the volume to a comfortable setting. If sound does not restore, please see the
Test the sound devices section of this document for more information.
NOTE: If the computer has a feature where you can slide your finger along a graduated strip above the keypad to change the volume, the capacitive touch mute button may become stuck in the muted position and prevent the playback of sound. To resolve this specific issue, download and install the latest BIOS for your particular computer model.
