A friend of the author has recently followed the trend and installed Win7. Recently, when chatting on QQ, he found that the other party could not hear his voice. He could hear the sound clearly using the system's voice recording function, indicating that his microphone was normal. of. I thought it was a problem with the other party's computer, but everything turned out to be normal using XP. This problem has troubled him for a long time, so the brave author took action and finally found the problem. Now I will show my shame here and introduce it to everyone in case of emergency.
Step 1: Install the latest driver, do not use the system’s own driver
Since the driver function of Win7 is much more powerful, this friend's laptop was automatically installed with the sound card driver after the system was installed. Moreover, when it is used to listen to songs and watch movies, the sound is normal. It is also possible to use the system recorder to sing a song or something. It was normal, so I didn’t pay much attention to it. However, this is very likely to be the problem, so it is recommended that everyone update their sound card driver. You can search and download it in the search engine.

Step 2: Set up the microphone correctly
After the driver is correctly installed, you still need to turn on the microphone function. In XP, you can simply click the small speaker button on the taskbar to set it, but the corresponding position has changed in Win7. Enter the "Control Panel", select the "Sound" item, and then switch to the "Recording" tab to see if "Microphone" is set as the default device. Of course, some sound cards may have multiple microphone options, so choose the correct one. "microphone".

Step 3: Turn off the microphone effect
Through the above settings, your microphone may sound normally, but if you find that the microphone sound is relatively small, you need to make detailed settings. In the "Recording" tab in the second step, double-click the default "Microphone" icon to enter detailed settings, switch to the "Level" option, drag "Microphone" to 100, and drag "Microphone Boost" to +30.0dB. If the sound is louder, you can adjust it. If the sound is lower, it is difficult to adjust. In addition, under the "Enhancement" tab, you can also disable all sound effects. According to many netizens, turning on these effects may cause the microphone to have low volume problems or even silence, so select "Disable all sound effects".

After testing by the author, the above operation can successfully solve the problem on software that requires the use of microphones, such as QQ, Duowan YY, and Sina UT.
