Laptop Trouble Tips
f No-Sound is coming from the computer, do the following:
If you are using self-powered USB speakers, remove the USB cable and plug it into a different USB port. If you are using outlet powered speakers and have a working set handy, replace the non-working speakers with the working pair to test. If you still have nothing..... let's move on to software. But one tip first: (for geeks and beginners).
Still No-Sound?
First check the speakers themselves, as many have a volume control on the speakers.
Next:
You should get the following:
Make sure that the software volume controls are not muted, and that the volumr levers are high enough to hear.
Still No-Sound ?
If you have an add-on sound card and none of the hardware or software fixes helps, you may have to replace the sound card. If you use on-board sound, it will probably pay to purchase an inexpensive sound card rather than a new motherboard.
BIOS
If you've been messing around in the BIOS, you may have disabled your on-board sound if that's what you're using. If you don't know what BIOS means, you probably haven't been there and can move on.
If everything is grayed out, go to step 8. If the "Mute" box is checked, un-check it. In "Device Volume" make sure that your volume level is set to a comfortable volume level for your speakers.
Click the "Sounds" tab. Under "Sound Scheme" check to see if "No Sounds" is selected. If it is, click "Sound Schemes" and a drop down list will appear. Select "Windows Default" as the scheme. To test your sound now, click on a sound listed below the "Program Events" window. These will be indicated by a small speaker icon located next to them. Simply left click the sound once, then click the play button. If you hear sound, congratulations. If not, move on.
Click the "Audio" tab. Under the "Sound Playback" option, make sure your sound card is selected as the default playback device. Usually, only one device appears here, unless you have multiple playback devices installed.
If everything is grayed out, you either do not have a playback device installed or your drivers are corrupted and need to be replaced. Drivers help hardware and software function together. Try this
fix for reinstalling drivers.
Right-click "My Computer" >
select "Properties" from the drop-down menu >
Click the "Hardware" tab and then click the "Device Manager" button. Device Manager will open.
If you have a red X, right click the device with the x and select "Enable" from the pop-up menu. Test your sound at this point. If you have a yellow question mark, right click the device, click "Properties" from the pop-up menu, and then click the "Driver" tab on the window that appears.
Now, click the button "Roll Back Driver" to go back to the previous drivers that were functioning correctly. Restart your computer at the prompt.
As a last resort, you can uninstall and reinstall the device. Right click the device and select "Uninstall" from the pop-up menu. Restart your computer. Windows will automatically detect and install your audio device upon boot-up
Check Power
Check both your computer and speakers are plugged in, have power, and are turned on. If the speakers are plugged in but do not appear to have any power, (look for a power light on your speakers). plug speakers into a different outlet. If you are using a power strip and find that you have a bad socket in the power strip, replace the power strip. Some speakers are self powered and use a USB cable to supply power. Make sure that the USB cable of your speakers is connected securely to the USB port of your computer.Check Sound Cable Connection
Once you have verified that you have power to your speakers, test the sound again. If you still do not have any sound, make sure the cable connecting the speakers to the computer (known as a 1/8" TRS cable) is plugged into the light green audio output jack on the PC. |  |

Hardware Failure
As it is with any troubleshooting process, the issue can sometimes come down to the hardware failure.If you have an add-on sound card and none of the hardware or software fixes helps, you may have to replace the sound card. If you use on-board sound, it will probably pay to purchase an inexpensive sound card rather than a new motherboard.
BIOS
