Re: No audio device detected
Ok when you plugged in the USB sound did it "see" it... did it ask for "Drivers" Because this device MUST have drivers.. also ya may have to disable any onboard sound device ya may have via the BIOS setup menu. Generally these USB sound devices are real easy to install and use.. try it on another PC to be sure it is OK.. GL

Do you have the AC adapter plugged into a live outlet and have you turned on the speakers? Make sure that the speaker signal cable is plugged into the correct port on your computer (the lime green port on a desktop). Check that the correct audio driver is installed for your computer. (With Windows 8, use the Device Manager to check. From the Start Screen, type in Device Manager. Click on Settings and then select Device Manager. Alternatively, Windows key+C on the desktop. Select Settings and then Control Panel. You can find the Device Manager under System and Security or Hardware and Sound.) Scroll down to the Audio devices. Expand the section and look for a red triangle with an X or a yellow triangle with an exclamation point. Try updating the driver (check with the manufacturer of your computer for the latest driver). Even if you don't see the error triangle, try reinstalling the latest driver.
Next check if the speakers work on another computer. If they don't work, the audio cable may be damaged. Try a different set of computer speakers on your computer. If other known good speakers do not work and the correct audio drivers have been installed, check the audio output devices. Go to the Control Panel > Hardware and Sound page (as described above). Choose Manage Audio Devices. Check if the HDMI port is set as the default audio device. Disable it for a bit (right click on the device) . Sometimes when a new video card is installed, the audio device defaults to this port. This messes up the drivers for the regular audio.) Reboot the computer and then try reinstalling the audio driver. Reboot again. If it still fails, there is probably something wrong with the audio device hardware. If you are using an add-on sound card, try disabling it and using the motherboard audio device. (A number of add-on sound cards didn't work well with Win7 or Win8. The on-board audio drivers worked better.) If you are using the motherboard audio on a desktop, try an add-on sound card. (Check for Windows 8 compatibility (drivers) before selecting any card.)
Have you check all the Volume setting on you computer?
On the lower right side look for the computer Icon check if there is a red X on the speaker Icon, if there is then it can be that here is something wrong with the speaker driver or it does not detect the speakers.
If you do not see the speaker Icon then the Driver for the Audio card is not installed on the computer and you may need to re install that Audio Card Driver to be able to regain the audio from your Speakers.
Also the speakers should connect to the Green Audio Jack behind the computer, if it is then still no Audio you can try the Audio Jack in front of the computer as well to check the Audio Card in the Machine, if the front and back audio jacks do not detect nor produce sound when the speakers are connected then re installing the driver for the Audio card may work, unless during the installation an error shows that the there is no audio device detected then it means the Audio Card is busted.
Let us hope not since it is very seldom an Audio Card could go busted.
I hope this helps.
Have nice day,
Hi, you need to check for problems with your sound driver. To do this go to start, control panal, system, then hardware and finally device manager. If there is a problem your audio device will be highlighted with a yellow ?. You will need to down load and install the latest sound driver for your system. If you are not sure which one; you can do a google search, or try the Realtek AC'97 sound driver, which is free to down load from a google search. Hope this helps.
I would first try to check for viruses and spyware. This is one of the major causes of sound issues. If everything else is ok with this laptop, then it sounds like your audio card might have a problem. Howver you might also have a problem with your speakers. Try connecting external speakers to you computer. If they work then it's your speakers. You can purchase those online from Ebay.
Speakers do not need any drivers!! Your sound card need drivers.
If your sound card is PCI, remove it and reinsert it to the PCI slot again and see whether your system detect the device and use the sound CD to install the drivers. (Change PCI slots if necessary and turn off the PC before changes the PCI sound card).
If your audio device is intergrated device, check the Bios to make sure the sound/audio is enable.
Note: Check the device manager first to see any audio device had been install properly.
Open control panel>> administrative tools>> computer management>> device manager. There u will find something like Sound, video and game controllers. Next, double click ur audio device and see that the device is working properly or not. If not, then install the drivers for the devices. If problem persists, type run in ur start menu search bar>> type "regedit" and press enter. Open the registry editor>>HKEY_CURRENT_CONFIG>>System>>CurrentControlSet>>enum>>HD audio(or like that, may vary with operating systems and mounted devices) and finally search through to SPEAKER CONFIGURATIO. See that the registry data is set to 4. If not, set it manually. If problem persists, contact service centre.
Whats happened is that your "Audio Drivers" have been removed. Your audio device is inside your PC /laptop, probably on a bit of your computer called the motherboard, but in order for your computer to recognise and talk to your audio device it needs a bit of software called a driver. We need to find out what type of PC / Laptop you have, make another post on here with as much info on you PC/laptop as you can find, and state that you are looking for the audio drivers, myself or one of the other experts will then find the right drivers for you and tell you how to install them
try a microsoft update to see if it can detect you have no audio device, if it detects it it will say in hardware after it checked your computer for updates, if this does not work then you need to go to the computer or motherboards manufacturers support website do download the driver
restart the computer so that the o/s can detect the audio device ,if after restarting it didnt work then check the status of your audio driver from the device manager if not detected reinstall if this didnt work then you know the spk is bad and needs replacement
