Step by Step troubleshooting to fix sound problems in computer
Check the physical connection
Surprisingly, a good percentage of sound issues are related to physical connection.
- Check if the power supply is turned on and the LED on the speaker is emitting light. If no light is coming, then check and confirm if power cable is connected properly.
- If the speaker is working properly, confirm that green connector on the end of the right speaker or in some cases sub-woofer is connected to Line Out. Alternately, to check if the speaker is having issue, connect headphone and check if sound is coming.
Check the speaker volume
Again, this sound silly. But a small portion of cases that I handle is as simple as turning on speaker volume.
- Check if mute is turned off. Increase the speaker volume.
- On the computer screen, check the speaker icon on the right side of task bar. Click on it and make sure the sound volume is increased to make it audible.
- If the speaker icon is missing,
- In XP, Control Panel à Sounds and Audio Devices Properties à Volume à Increase the volume under “Device Volume”. You can also place the speaker volume in task bar by checking “Place volume icon in the taskbar”.
- In Vista and Win 7, Right click and select “Start (Windows Pearl)” properties ,Taskbar Notification Area. Select the option to show speaker.
Check if the device driver is installed properly
Check device manager.
- Click Start > Run > Type “devmgmt.msc”
- This will open up Device Manager. Check for “Sound, Video and Game Controllers” . If there are no entries, the sound card might be missing the device driver and needs to be installed. How to find drivers for unknown device?
- If any entries below Sound, Video and Game Controllers shows a yellow “!” sign, it might be a device driver conflict or driver compatibility issues. It can be fixed by re-installing the proper device driver for the sound card.
- If any entries show, a red “x” sign or arrow pointing downwards, it shows the device is disabled. Right click on the entry and enable it.
If the sound card is still not working, the issue is related to sound card. You may need to replace the sound card.
