What happens when the computer motherboard can t output sound? 5

Take a look at it according to your situation.

Now there are two kinds of BIOS commonly used in motherboards, "AMI and AWARD", and their definitions are slightly different due to different manufacturers.

1 Short: The system starts normally. Congratulations, there is nothing wrong with your machine.

2 Short: General error, please go to CMOS Setup and reset the incorrect options.

1 long and 1 short: There is an error with the RAM or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard.

1 long and 2 short: The display or graphics card is wrong.

1 long and 3 short: The keyboard controller is wrong. Check the motherboard.

1 Long 9 Short: Motherboard Flash RAM or EPROM error, BIOS corruption. Try a different block of flash ram.

Constant ringing (long sound): The memory module is not plugged in tightly or is damaged. If it still doesn't work, you can only replace a memory module.

Repeated, short ring: There is a problem with the power supply.

No sound and no display: There is a problem with the power supply.

Below is the alarm tone for the AMI BIOS**:

1 Short: The memory refresh failed. Replace the memory module.

2 Short: The memory ECC verification error is incorrect. Setting the memory option for ECC check to Disabled in CMOS Setup will solve the problem, but the most fundamental solution is to replace a memory.

3. Short: The basic memory of the system (the first 64KB) failed to be checked. Change memory.

4 Short: The system clock is wrong.

5 Short: Processor (CPU) error.

6 Short: Keyboard controller error.

7 short: The real mode of the system is wrong and cannot be switched to protection mode.

8 Short: A memory error is displayed. If there is a problem with the display memory, try changing the graphics card.

9 Short: ROM BIOS check and error.

1 long and 3 short: memory error. If the memory is damaged, it can be replaced.

1 long and 8 short: A test error is displayed. The monitor cable is not plugged in properly or the graphics card is not plugged in properly.

1. If the computer can't start, either the memory is loose or the graphics card is loose.

2. "Didi." Continuous short tones.

In general, it is common for the host computer to have a power supply problem. However, sometimes when the output voltage of the power supply is low, the host does not report it.

However, there will be a situation where the hard disk is lost, the reading performance of the optical drive is poor, and it often crashes. When these situations occur, it is best to check whether the output of each voltage is low, when +5V and +12V are less than 10%, the above problems will occur from time to time. Because the power supply has a voltage output, it is often mistaken for a problem with the motherboard or the hard disk, and a lot of time is wasted.

When the DC component is reduced, the high-frequency AC component in the power supply increases, which will interfere with the normal operation of the motherboard, resulting in system instability, and it is easy to crash or blue screen.

3. "Tick." Backbite. 's continuous, spaced long tones.

It is the sound of memory alarm, generally due to loose memory, poor contact between the gold finger of the memory and the memory slot, oxidation of the gold finger of the memory, and a fault of a chip in the memory.

1. Check whether the sound card driver is complete, the sound card may be set up incorrectly if the driver is complete.

Second, the sound card driver is complete, the sound card settings are also set, or there is no sound, try a different sound card.

1. Poor contact: The internal circuit is aging due to the use of the speaker for too long, and there may be no sound when the speaker is connected to the computer. Check whether the audio connection is normal, make sure that there is still no sound after it is intact and you can install the driver to see, if the driver is not good after installation, it means that the audio is broken.

2. Voice coil break: you can use the multimeter 1 gear to measure the speaker lead wire solder lug, if the resistance value is , you can use a knife to scrape the sealing paint of the lead wire at both ends of the voice coil, expose the bare copper wire and then test, if it is not through, the voice coil is broken internally. If it is through but there is a click, it means that the voice coil lead is broken, you can solder the thread well, and then use a piece of enameled wire similar to the voice coil winding to solder it properly.

1. Click the volume icon on the taskbar to check whether it is muted.

2. Check whether the sound card, speaker and other equipment are damaged and whether the connection is regular; Remove the independent sound card, use the eraser gold finger, plug it tightly, or change the slot; If there is a problem with the board, shield the card and replace it with a separate sound card.

3. Check the sound card driver

1. Right-click on "Computer" -- Properties -- Hardware -- Device Manager, "Sound, ** and Game Controller", if there is a yellow "? "The sound card driver is missing, there is"! ", indicating that the sound card driver is incompatible.

2. Use the original CD-ROM installation of the computer, put the driver disc of the sound card into the CD-ROM drive, and right-click under "Sound, ** and Game Controller". select "Update Driver", open "Hardware Update Wizard", select "Yes, only this time" --Next--Automatically install the software"--Next", and the system will automatically search for and install the sound card driver in the disc.

1. The audio driver is not installed, if there is an installation disk, you can click on the corresponding sound driver to install it, and restart the computer. If you don't have an installation disk, you can check the PC Manager hardware and then install the missing driver.

2. The audio service was stopped and banned.

The bottom left corner of the window icon is required. Click -> Enter to find the Window Audio service on the right.

Right-click -> Properties -> set to start automatically (otherwise you need to set it up next time you boot up)-> and then click Start and wait for a while.

3. Speakers are disabled in the sound options.

But if all the audio input on the computer is normal, but there is no sound, this depends on whether your voice is turned on.

Everything audio production is working fine or there is still no sound to say. It can only mean that the sound driver is normal,1,See if it's plugged in the wrong hole and the connection cable problem,2,Try to see if there is a problem with the sound in another way,3,If there is a problem with the computer sound card, you can buy a U disk port sound card,Plug it in and you can use it。

It is recommended to change another earphone to listen to it, if the sound is normal, it is positioned that there is a problem with the original external equipment, and it is recommended to replace the external equipment. The above is 'Computer Audio Service is not running, how to solve the problem that there is no sound in the audio output.'

Hello: 1, the computer audio output is [1vpp standard audio signal], if youOKIf all the outputs are normal, it should be [Active speakers] is out of order.

2. Please check the active speaker's [Power supplyIsn't it normal? 【Audio signal cablesIs it intact?

Check the hardware to make sure it's okay. It may be that it's time for the driver to update. Right-click on your computer, open Properties, open Device Manager, look at Audio** and Game Drives, and if there is an exclamation mark or missing, you should update the driver.

If there is no sound, then you need to check whether the output device is normal. Because the audio is normal, then as long as the output device is normal, there will be sound. Unless the device is damaged, then there is no way to make a sound, and the output device must be replaced.

How do you know that the output is fine? Since it's normal, it's that the horn is broken, check the hardware to confirm that there is no problem. It may be that it's time for the driver to update.

Everything is normal on the desktop computer, there is no sound, it means that there is no problem with your driver or something, it is caused by the lack of speakers on your desktop computer, you can try to plug in a headset to see if there is any sound that should work normally.

There may be a conflict between the sound card, first go to the device manager to see how many sound drivers there are, there are more than two, then you can disable one and try it.

If the sound card driver is damaged, reinstall the sound card driver that is compatible with the system with the universal driver, and then restart the computer, and there will be sound.

Try reinstalling the sound card driver, or set it to traditional mode in the audio settings.

All audio input on the desktop computer is fine, but there is no sound, which should be due to improper settings. So, first open the control panel of your computer, then find the sound settings option, click on it, and then unactivate the setting to disable the use of speakers.

The audio output of the desktop computer is normal, there is no sound, check the link line, and plug it in a few more times. It may also be that the HDMI line integrates the audio output function, and the speaker output should be selected on the audio controller side to have sound.

If all the audio output of your desktop computer is normal, but you can't hear the sound, it may be the reason why your ears can't hear the sound.

If the audio output is normal and no sound can be heard, then it is possible that there is a problem with the speakers, wiring, or speakers

Well, the desktop computer sound should be equipped with the corresponding audio or headphones, and the chassis and monitor themselves do not have external equipment.
