I hope this post script can help you to identify and fix common sound problem in Windows, including no sound coming from your speaker
or headphone.
One of the most common issues experienced in computers is "no sound" problem. The issue can be due to incorrect volume settings, cable connections not connected properly or corrupted audio drivers, sound settings, missing update and may be a problem with your sound card. For the best result just follow three steps below
Step 1. Check Hardware
Step 2. Test with different Audio Applications
Step 3. Use a Troubleshooter
Step 4. Update Driwers or Download New Drivers
Step 1: Check hardware
In our experiences, many sound problem are caused by hardware that's not set up properly,
Many sound problems are caused by hardware that isn't set up properly. What would you should do, just follows the steps below:
Check the cable and make sure that the cables are connected properly Speakers and headphones If you're using external speakers, make sure that they are correctly connected to the computer. Many computers have three or more jacks that connect to a sound card or sound processor, including a microphone jack, line-in jack, and line-out jack. Your speakers should be plugged in to the line-out jack. If you're not sure which jack this is, try plugging your speakers in to each of the jacks to see if any of them produce sound.
If you're using headphones, make sure they aren't plugged into the line out (headphone) jack of your sound card or computer (unless you want to be listening with headphones rather than speakers). When you plug in headphones, most computers automatically cut the sound to the speakers.
USB audio devices
If you’re using a USB audio device and also have an internal audio device installed, try these basic troubleshooting steps: Unplug the USB audio device and restart your audio program. Test for sound using the internal audio device. If you hear sound, there might be problems with the USB audio driver or with Windows not using the USB audio device as the default audio device. Close all audio programs, unplug the USB audio device, wait for the USB driver to be uninstalled (this should happen fairly quickly), plug the USB audio device back in to the USB port, wait for the driver to load, and then start the audio program and check for sound. Check that you have the correct audio device set as the default in Windows and in the program. Check the audio device manufacturer’s website for updated drivers.
1.2. Check your sound card
Check to make sure your computer has a sound card, or sound processor, and it's working properly. Open Device Manager by clicking Start, pointing to Control Panel, clicking System, clicking the Hardware tab, and then, clicking Device Manager. Double-click Sound, video and game controllers to expand that category. If a sound card is listed, you have one installed. If no sound card is listed, check the information that came with your computer to see if there's supposed to be a sound card installed. If there should be a sound card installed, you'll need to install one according to the manufacturer's instructions.
1.3. Check power and volume
If you have speakers, make sure they're plugged into a working power source and turned on. Make sure that your speaker volume or headphone volume isn't muted or turned down too low. This is particularly important for laptops, which often have small speakers that can be hard to hear.
Click Start, point to Control panel, and then click Sounds and Audio Devices. Under Device volume, move the slider to the right to increase the volume. Make sure the Mute checkbox isn't selected.
Click Speaker Volume, and make sure the sliders aren't set to Low.
1.4, Audio Icon Missing
If your audio icon is missing from the task bar
Click on Start menu and select Control Panel
If you are Classic View, double click on “Sounds and Audio devices” and select the checkbox beside
Place Volume icon in the taskbar and click on OK.
Step 2. Test With Different Audio Application
It would be better if you could test with different audio application such as Real Player or VLC Player
Step 3: Use a troubleshooter
A troubleshooter is an automated tool that can find and automatically fix some problems with your PC.

Step 4: Update Drivers or Download New Drivers
For Windows to recognize your sound card or sound processor, you need a compatible driver. Most sound cards and sound processors require driver software to work properly. Outdated, incompatible, or damaged sound card drivers can disrupt communication between the computer and the sound card. If you recently upgraded from one version of Windows to another, it's possible that the current sound card driver was designed for the previous version of Windows. If you've had recent power outages, viruses, or other computer problems, it's possible that the drivers have become damaged. Downloading and installing the latest sound card driver for your sound card can help resolve these types of problems.
Here are two ways to find and install a driver:
- Use Windows Update.
You might need to set Windows Update to automatically download and install recommended updates. Installing any important, recommended, and optional updates can update system features and other software that might help fix your sound problems.
Automatically Update Drivers using Windows Update
1. Open Automatic Update by clicking Start, pointing to Control Panel and clicking Automatic Update.
2. Click Automatic and select the day and time to download update
3. Click Apply
- Install Software
It may come with a disc or download direct on websites
To download and install a driver yourself
If Windows can't find a driver for your sound card or sound processor, and the device didn't come with driver software, you can look for a driver on the manufacturer's website. Driver updates are often available in the support section of such websites. To locate the driver, find the manufacturer and model name or number of your sound card, and then visit the
Hardware and software vendor contact information website.
