You may usually encounter this problem, don't be nervous, the reasons for the failure of the computer sound card are nothing more than a few, let us take you to analyze the causes of the failure of the computer sound card and how to deal with it.

There are three main reasons for the failure of the computer's sound card, one is that the relevant services are not turned on, the second is that the sound card driver is not installed or does not match, and the third is the hardware problems such as the motherboard and the sound card. In view of these three situations, the following is the origin to share the solution for you.

Reason 1The service is not enabled.

Right-click [Computer] [Manage];

Click [Service];

Find the Windows Audio service on the right side and double-click the mouse.

In the properties that appear, select [Auto] for [Startup Type], select [Start] for [Service Status], and then click [OK] below, and finally open the ** device to test whether there is any problem with the audio.

Reason 2The sound card driver is not installed or does not match.

Right-click [Computer] [Properties] [Device Manager] to see if there is "?" under the [Sound Card, ** and Game Controller] option"Logo or"!If there is no driver installed, it shows that there is an unknown device.

If this area is displayed as "Symbol Status", it means that the computer is missing the sound card driver, and then we can use the driver wizard to automatically update the sound card driver.

Reason 3Hardware issues such as motherboards, sound cards, etc.

If the above methods do not solve the problem, it is likely that the sound card hardware itself is a problem. If it is a hardware problem, it is better for non-professionals to go to a professional computer repair shop for repair.

Well, the above are the three main reasons for computer sound card failure and how to deal with it, you just need to follow the above steps, I hope to help you eliminate the cause of computer sound card failure.

1. The connection between the output device and the interface is abnormal.

It is recommended to replace another earphone audition, if the sound is normal, it is positioned that there is a problem with the original external equipment, it is recommended to replace the external equipment; Check whether the audio device interface is properly connected to the output port (usually the green port) of the chassis.

2. The sound card driver is not installed or does not match.

Right-click [Computer] [Properties] [Device Manager] to see if there are abnormal signs such as "yellow question mark" or "yellow exclamation mark" under the [Sound Card, ** and Game Controller] options, or if there is an unknown device displayed when the driver is not installed. If the area is displayed as "Symbol Status", it means that the computer sound card driver is missing, and then you can use the driver life to solve the problem.

3. The relevant services are not enabled.

Right-click [My Computer] [Management] service, find the [Windows Audio] service on the right and double-click, in the properties that appear, select [Auto] for [Startup Type], select [Startup] for [Service Status], click [OK] below, and then open the ** device to test whether the audio problem is solved.

4. Realtek Audio Manager is not set up.

Take Win7 as an example: Detect whether the Realtek audio settings are normal. Click the "Control Panel" item, click the "Realtek Manager" item, click the jack settings in the upper right corner, and tick "Disable front panel jack detection".

Go back to test if the audio issue is resolved. The steps are similar for XP and Win8 systems.

5. Hardware problems such as motherboard and sound card.

If none of the above settings solve the problem, it's a problem with the hardware itself. If it's a hardware problem, go to a professional computer repair shop for repair.

First, first confirm that the hardware is fine. If the speaker is fine, the sound card is fine, and if you've tested it on other machines and it's really good, then you can read on.

2. Make sure all the cables are exactly right. Then power on the speaker and turn on the volume switch.

3. Install the driver of the sound card correctly, if it is an onboard sound card, it is best to install the driver provided on the driver disk of the motherboard. (Actually, the computer doesn't make a sound, and many times it's because the sound card is not driven correctly.) In general, after the sound card driver is installed, there will be a small speaker icon in the taskbar in the lower right corner.

Fourth, if you are sure that the driver is installed correctly, then take a look at the volume settings in the computer. The specific method is to double-click the speaker icon in the taskbar, and check whether the volume is turned off to the minimum in the "Volume Control" and "Waveform" dialog box in the pop-up "Volume Control" and "Waveform".

If these two options are not available in the dialog box, click on the "Options" menu - select "Properties" - select "Volume Control" and "Waveform" in the "Show Volume Controls" and then set them correctly. Note: Step 4 can only be set up after the driver for the sound card has been installed correctly.

If the sound card hardware is damaged, it cannot be repaired with software, and can only be repaired, of course, the sound card on the market is not expensive, you can consider buying a new one, and the repair cost may be higher than the purchase**.

If the sound card driver is faulty:

Open the software manager --- search: Driver Life---**After installation--- driver management--- backup all drivers (be prepared, so as not to fail the update, you can restore the driver) -- and then click on the local driver ---select the public driver) to update the sound card driver---**Restart the system after installation.

Note: If there is no problem, don't update the driver to avoid problems! 】<

3.If you don't have sound yet, you can open the sound card controller to set it up (or the Realtek HD Audio Manager.

Hi-Fi Audio Manager) :(take win7 system desktops as an example).

First, check if there is a sound icon in the bottom right corner of your computer. If there is a sound icon that indicates that there is nothing wrong with the sound card installed on the computer, we will check if the sound is turned to the lowest or muted.

FM synthesis chip low-end sound cards generally use FM synthesis sound to reduce costs. The role of the FM synthesizer chip is to produce synthesized sounds.

The Waveform Synthesis Table stores sound samples of the actual musical sounds in the wavetable ROM for use by MIDI. Generally, mid-to-high-end sound cards use the wavetable method, which can obtain a very realistic use effect.

Basic Structure:

Sound control chipThe sound control chip is to obtain the sound analog signal from the input device, convert the sound wave signal into a string of digital signals through the analog-to-digital converter, and sample and store it into the computer. When playback, these digital signals are sent to a digital-to-analog converter to be reduced to an analog waveform, amplified and sent to a loudspeaker to emit sound.

DSP chips are programmed to perform a variety of functions. It can handle commands about sound, perform compression and decompression programs, add special sound effects, fax modem, and more. It greatly reduces the burden on the CPU and accelerates the execution of multi-** software.

However, low-end sound cards generally do not have DSP installed, and high-end sound cards are equipped with DSP chips.

Sorry, I've kept you waiting, I've helped you check it, if there is a problem with the computer's sound card, you can try the following two methods to check whether it can be fixed: Method 1: 1. Right-click on this computer and select manage; 2. Services and applications, click Services, find Windows Audio Service on the right side and double-click to open it; 3. In the properties that appear, select the startup type Automatic, select the service status to start, and then click OK; Finally, open the ** device to test whether there is any problem with the audio.

Method 2: 1. Right-click on the computer and select properties; 2. Then click Device Manager; 3. "Sound, ** and game controller" to see if there is"?"Logo or"!

logo, if there is a description that the computer is missing the sound card driver, you can use the driver wizard to automatically update the sound card driver.

If the above two methods can't solve the problem, you need to go directly to a professional repair shop for maintenance, generally just replace the sound card with a new one.

I hope mine will help you.

**Driver wizard installs and runs the program, he will automatically detect all the drivers on the computer, select the sound card driver to install, and especially remind not to choose other driver updates, especially the motherboard driver, do not update casually. Just select the sound card driver and you're good to go.

Then you can install the next driver on the Internet, and you must correspond to the model! Or use the Driver Wizard 2009 to install the driver. Hope mine didn't disappoint you! Thank you, please give points and status!

Now the Cron system installation disc comes with its own boot program, including the sound card installer, and the solution is very simple, just reinstall it. If not, the sound card may be faulty.

If the driver is damaged, update the driver again, and if the sound card hardware is broken, you have to replace it.

Install a driver wizard and drive the sound card.
