Where does the cough come from?

Cough sounds from computer speakers may come from:

1. System sound scheme prompt tone: As long as you have set the operation or the system has some problems, the preset sound in the sound scheme will be played. If changes are needed, you can do the following: Go to Control Panel-Sound and Audio Devices, set the original Sound Scheme to Mute, or modify each item in the original sound scheme and save it as a file.

2. Prompt sounds set by application programs: for example, the prompt sounds of QQ system, such as "Ding Ding Ding" when friends are online, "Didi Di" when friends talk, and cough when sending system information. If you need to modify or cancel, you can go to the Settings tab in the main control panel of QQ to make relevant settings. Other applications operate similarly.
