How to turn off the microphone

Cctalk turns off the microphone: Open the sound property panel to see which item is turned off or muted. If you really can't, upgrade the sound card driver and redo the system. If you don't study, you have to change a machine.

After the mobile phone version enters the personal center, click Settings to try to turn up the volume, or if your headphones are broken, you can ask their administrator! I also encountered such a problem when I was listening to the course of Taoyu.com, who specializes in French training for Japan and South Korea. I quickly contacted their administrator, and they immediately helped me, both efficient and responsible!
