A recent friend of mine asked me why the win7 system had no voice and looked at the data online and found that a lot of people were asking, " here's the information compiled on the internet, hoping to solve their problems。
For win7 microphones, there is no sound, and the writer generally begins from three sources:
1. Computer voice set-up issues;
2. Sound card-driven issues;
3. System services issues。
I. Examination of computer settings
Step 1: open the control panel to "hardware and sound" to "audio management devices"
Enter win7 control panel
Access to audio management equipment
Step 2: double-click "micro" into "micro properties" and then we choose "level" to adjust the microphone volume

If the microphone is set to be silent, no matter how big it is, it's useless, so it's best to set the microphone to maximum。
Ii. Inspection of computer soundcard drivers
Step one is clear, and we're going to check if the drive is wrong, and the simplest is to access the device manager to see if the soundcard drive is normal, and you can download the latest driver check the updated soundcard drive, preferably up to the latest version, some win7 systems, and because of the lower soundcard version, mike's voiceless。
Check and upgrade soundcard driver
See if the win7 audio service is on
It's best not to solve all the above, so let's check whether win7's voice service is disabled, right-click on the computer in the start menu, choose management, enter the service options, find windows auto and make sure it's active
Win7 audio service open
Win7 microphones have no sound, which is usually the three above. If none of the above is working, make sure that your computer has a microphone. For most notebooks there is a microphone, but no desktop, which needs to be used with microphones or related equipment。
That's why the microphone doesn't have a sound, and i hope it will help you. Please continue to monitor the lack of sound on the microphone。
