What should I do if the microphone cannot speak under the Win7 system?

Method 1: Install the latest driver

1. Because Win7 has a lot of powerful functions, the notebook is automatically installed with the sound card driver after the system is installed. Usually we listen to songs and watch movies. The sound is all right, recording with the system recorder is normal, but this is probably the problem, so I suggest you update your sound card driver. You can go to the motherboard manufacturer's official website or the driver's home drive center to search for downloads, or you can download the driver wizard to update the latest drivers.

2, after the driver is properly installed, you need to turn on the microphone function. In Windows XP, you can easily click the small speaker button on the taskbar to set it, but the corresponding position in Windows7 has changed.

3, click on the "Start" menu, go to the "Control Panel", select the "Hardware and Sound & Rarr; Sounds" option, pop up the sound dialog box, and then switch to "record" & rdquo; Tabs to see if you have set "Microphone" as the default device. Of course, some sound cards may have multiple microphone options, so choose the correct "Microphone".

Method 2: Set the microphone correctly

1. After installing the latest version of the sound card driver, your microphone may have sounded normally, but if you feel that the microphone sound is small, you still need Make detailed settings. In the “Record” tab, double-click the default “Microphone” icon to enter the detailed settings, switch to the “Level” option, and drag the “Microphone” to 100, “Microphone Enhancement” Move to +30.0dB, the sound can be adjusted when the sound is too large, and the sound is small and it is not easy to adjust.

2, in addition to the "Enhanced" label, you can also disable all sound effects, according to the reflection of many users, opening these effects may cause the microphone to have a small volume or even silent, so select “ Disable all sound effects & rdquo;

Method 3: Set the microphone volume

Enter the audio manager of the sound card, & nbsp; Recording volume & rdquo; In fact, has been set previously. And "play volume" is the sound that the speaker plays to capture the microphone. The default is to minimize. The "Noise Rejection" and "Echo Cancellation" functions below must be selected. These two functions are very helpful for improving the sound quality.
