Computer Sound Troubleshooting
Humming noises, warped static audio and the lack of sound are all common issues that require sound device troubleshooting. If your computer is set too close to other electrical equipment, a humming noise can be generated due to the combined excess voltage. Static and distortion can be the effect of the computer's volume default settings being set too high. And when there is no sound emitting from the device at all, making simple software adjustments may be all that is needed.

Create and work with a sound troubleshooting checklist, working backwards by first identifying the effect and then the possible origin. The solutions that were implemented will eventually tell you what works and what doesn't by their resulting failure or success.
Check the volume button or wheel on your computer, which should be located on the top or around the front area. After that, check the sound software. Access the "Volume" icon located on the computer taskbar. Right-click on the "Volume" icon. Uncheck any boxes next to "Mute" in all of the sound categories. Adjust all sliders to mid to mid-high levels and retest for sound. To curb repeated troubleshooting, check off each attempt from your troubleshooting list as each sound solution is tested and indicate if the issue was solved or not.
Review the properties of the speakers by selecting the "Sounds and Audio Devices Properties" category after right-clicking on the "Volume" icon. Adjust the device speaker settings by moving the sliders to a higher level. This area is also where you can click the "Advanced" button and then go to the "Performance" tab to adjust the "Sample Conversion" rate of sound for better audio quality output.
Connect the computer to the Internet if it not already activated. While still in the "Sounds and Audio Devices Properties" dialog box, go to the "Hardware" tab to check the audio drivers. Select each one separately and then click the "Troubleshoot" button for each audio driver separately. To update the audio driver, click on the "Hardware" tab again and then click on the "Properties" button. Select the "Driver" tab to locate the available driver selections of "Update", "Rollback" or "Uninstall".
Update the driver and then retest the audio. You may need to rollback the driver if the update fails. And if this happens, check the computer manufacturer's website and see if a driver is listed for downloading. Up to-date news and product information should be available from their website as well.
Note that updating a driver separately will not necessarily be the only needed solution to resolve all of your audio issues. Find out if the computer needs a hotfix or the system requires an update by going to the "Windows Catalog" website.
Lastly, before resorting to replacing the sound card, check with the manufacturer for a list of compatible ones so that down the line audio issues will be lessened and your investment lengthened.
