There is no sound on the computer, urgent! Correct answers add extra points!

There is no sound from the computer:

If there is no sound on the computer, you can analyze it by following the steps below:

First, first confirm that the hardware is fine. You've already said that 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.

In fact, the computer does not make a sound, and many times it is because the sound card is not driven correctly. In general, after the sound card driver is installed, the task is in the lower right corner.

There will be a small horn icon in the bar. ）

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 it doesn't work, change the motherboard! There's no sound in the device manager either? There may also be a system problem!

Lenovo Intelligent Interaction System.

Are all the drivers installed on your Device Manager? Are there any exclamation marks or question marks? Is the driver the corresponding driver for your operating system?

You borrow a speaker and try it, and the alarm is a small speaker on the motherboard, and this speaker can only make a beeping sound, and no other sound can be made.

Sometimes after plugging in the headphones, I unplug the cable and use the speaker and there is no sound, I used to sometimes do this, after unplugging, you have to set the default device to the speaker, so that you can try it.

The seizure of the impact may be broken, or you have muted the computer, and there are only two possibilities.

The sound of the alarm is not the same thing as the speaker, the alarm sound is emitted from the motherboard of the computer.

It's likely that the speaker is broken!

Have you taken a look at the sound card driver?

If you're so sure that none of the problems you've envisioned don't exist, then I'll add a few that I hope will help.

On the onboard sound card, disable the device. Then uninstall the device driver. Turn off your computer and turn off the power. Unplug the cable between the motherboard and the power supply.

Start the machine after three minutes, before connecting the cable between the motherboard and the power supply.

Start your PC and watch for Explorer. Is the sound card part a question mark? It doesn't mean that the motherboard is broken. If the mammoth orange is late, reinstall the driver. And make sure that the BOLS on the motherboard is not in the state of shielded sound card.

After the driver is installed, restart the computer. Test if the sound is repaired.

If it is a discrete sound card, you can uninstall the sound card driver first, enter the BOLS and use the onboard sound card to start the discrete sound card. And remove the independent sound card with the power plug short, and replug it into the motherboard. Connect the power to turn on, such as the above process, there should be a question mark in the device pipe, and it should be solved after installing the driver and restarting, otherwise, your motherboard will be sentenced to death.

and asking questions are all learning processes, please Wu Ran correct your attitude towards asking questions, otherwise you will be domineering. This question is giving.
