The onboard sound card suddenly lost its sound!!

1.If the "Little Speaker" icon in the right corner of the screen is not there, the sound card is broken or the sound card driver is lost, please try to reinstall the sound card driver.

2.If the problem persists after reinstalling the sound card driver, the sound card is broken.

Type dxdiag in the runtime, open the directx diagnostic tool, and look at the instructions in the sound, if you don't say that there is no driver, or the driver is broken, you have to re-drive it

Since there is a sound, it proves that the driver has hit

It is possible that the order of the driver is wrong

Re-uninstall and re-type.

Is the CPU overclocked? Overclocking can cause problems with the onboard sound card.

If there is no sound, give priority to whether the sound card driver file is damaged, and if there is no sound after installing the sound card driver, it is the problem of the sound card.

1: Right-click "My Computer" - Manage "- Device Management" to see if the sound card on the right is good, it is recommended to update or reinstall the driver.

2: Click on the small speaker in the lower right corner of the desktop to enter the volume control, see if your volume is at the maximum, and whether it is checked on Mute.

3: Is your audio wiring in good contact, is the volume button on the panel adjusted, is there a problem with the audio?

If you see a question mark in the device manager, it means that the driver is not safe, if not, check the speaker, if it is not broken, double-click the speaker icon in the lower right corner to see if there is any sound that is turned off.

According to you, there should be no jumpers and the like. And there is no problem with the system driving the sound card.

Now only the most troublesome troubleshooting method can be used to confirm the fault:

1.The current system does not move, just uninstall the driver part of the sound card, and then restart it to see if it can be restored.

2.Back up your important files, format the C drive, and reinstall the system.

If this does not recover, it is almost certain that there is a minor problem with the motherboard. And such small problems are generally more troublesome and need to be sent for repair. The repair fee is not expensive.

You double-click to see if the volume of the waveform is the lowest.

No, take a closer look at the motherboard to see if there is ash or other debris.

Kindness! I haven't seen the integrated sound card break either! Is it good to see the drive!?

Check the contact, this is fine, no, + a separate sound card is not very much.

Check that the lower plug is not plugged incorrectly; Is the sound switch turned on to the maximum? It feels like you're somewhere with bad contact.

Well, I've had this problem before. The solution is to reassemble the system

Title. The little crab alc889 on the board, it was all fine before, just for two weeks, it was always used by the computer, and suddenly it was silent, and then after a few minutes to a few hours, there was a sound again, and the cycle repeatedly.

The system is win7x64 sp1,Wiring or something is definitely no problem,In addition, the following efforts have been made:

1. Changed n drivers, including returning to win7's own driver;

2. Change the motherboard BIOS, and restore the factory settings, it was overclocked before, and now the default settings are not exceeded;

3. Reinstall the system, the system is a pure version and a non-GHO version;

4. Change the power supply of the computer.

When there's no sound,The system tray icon or something is still there.,I can't see anything abnormal in the device manager.,It's like the audio cable was suddenly unplugged.,There's no warning when the sound recovers.。。。
