How to Fix No Sound on an Acer 5920 Laptop With Windows Vista Home Installed

Sound problems on laptops such as the Acer Aspire 5920 can be frustrating and sometimes difficult to troubleshoot as notebooks are typically more difficult to diagnose and repair. Most sound problems in Windows Vista are correctable with just a little patience and attention to detail.

Turn off your computer speakers, then power them back on again. Unplug the speaker cable plug from the audio port on the PC and reinsert it. On most computers the plug should go in the green line-out port.

Click the small speaker icon in the lower left-hand corner of the screen and next to the Windows Vista clock display. Ensure that the "Mute" option in the volume control panel is clear and has no check mark.

Click "Start" and then "Control Panel," then click "Hardware and Sound." Check to ensure that the volume slider control is not in the "Low" position all the way to the left. If it is, increase the speaker volume by clicking-and-dragging the slider control to the right.

Click "Start," and then right-click "Computer." Click "Properties" when the pop-up menu appears. Click the "Device Manager" tab in the left side of the "System Properties" window.

Click the "Sound, video and game controllers" value setting in the Device Manager Hardware list. If the list does not display a sound card or adaptor, or if the sound card has a yellow exclamation mark next to it, you must reinstall the sound driver software for your motherboard or sound card.

Insert the Acer driver installation CD into the CD/DVD drive. When the installation wizard screen appears, click "install" or "set-up" to reinstall the sound drivers for the motherboard or sound card. After installing the drivers, restart your computer.

If you do not have the installation CD, open your Web browser and visit the Acer website to download the latest Windows Vista sound drivers for the Aspire 5920. Double click the driver file and follow the on-screen directions to install it on your computer.


If the above actions do not restore sound on your Acer 5920 laptop, browse to the Microsoft Support website and run the "Microsoft Fixit" utility to diagnose and repair other common sound problems in Windows Vista.


If all else fails, the sound issue is likely a hardware problem. Contact Acer for additional information.
