Hello everyone, Lin Fei to answer the above questions, windows7 no voice how to restore, windows7 no voice many people do not know, now let's take a look!

Recently, a friend asked me why the microphone of the win7 system has no sound. I looked up the information on the Internet and found that a lot of people were asking. The following is the information that Bian Xiao collated online, hoping to solve the problems of these people.

For the Win7 microphone without sound, the author generally starts from the following three aspects:

1. Computer sound setting problem

two。 Sound card driver issu

3. There is a system service problem.

First, check the computer settings.

Step 1: open the control panel hardware and sound and audio management devices, as shown in the following figure:

Enter the Win7 control panel.

Enter the audio management device

Step 2: double-click "microphone" to enter "microphone Properties", then we can adjust the microphone volume by selecting "level", as shown in the following figure:

Once the microphone is muted, no matter how loud the volume is, it is useless, so it is best to turn the microphone up to maximum.

Second, check the computer sound card driver.

Once there is no problem with the first step, let's check to see if there is a problem with the driver. The easiest thing is to go to the device manager to check whether the sound card driver is working properly. Once you can download the latest driver wizard to check and update the sound card driver, it is best to upgrade to the latest version. In some Win7 systems, due to the lower version of the sound card driver, there will be no sound like a Mike.

Check and upgrade the sound card driver

Third, check whether the Win7 audio service is enabled.

The best aspect has not been solved. Let's see if Win7's voice service is disabled. Right-click the computer project on the start menu, select manage, go to Service options, and locate the Windows Audio project to make sure it remains open, as shown in the following figure:

Is the 7 win 7 audio service turned on?

7 Win7 microphone has no sound, usually in the above three cases. If none of the above three measures work, make sure your computer has a microphone. Most laptops have built-in microphones, while desktops don't, so you need to use headphones or related devices with microphones.

That's why the microphone doesn't sound. I hope I can help you. For more information about why there is no sound on the microphone, please follow us.
