My computer has no sound and the taskbar sound icon disappears. What should I do?

This afternoon, I was a little sleepy, so I wanted to listen to the songs and start listening quietly, huh? No? I can use other players to enable it without sound. How can a computer suddenly have no sound? Look at the taskbar, the small horn icon has disappeared, open the control panel --> sound and audio devices, wow, there is no audio device, isn't my sound card broken? No way. If there is sound in the morning, right-click my computer --> properties --> Device Manager and check the sound, video, and game devices. It's normal. There is no exclamation point, what's going on? In the first place, I thought the driver was broken, so I re-installed the driver. No, I deleted the sound card and re-installed it. I still don't know. My God, what happened ???
After checking on the Internet for a long time, I finally heard the sweet song of Ben.
Symptoms: 1. There is no small horn icon in the taskbar.
2. Control Panel> sound and audio devices> volume. All options are dimmed and "no audio device" is displayed ".
3. Right-click my computer and choose Properties> Device Manager. Everything works.

Solution: 1. First confirm that it is not a sound card drive problem.
2. Run services. MSC to open the service, find the service: Windows Audio, start it, and restart it. If it cannot be found (usually it cannot be found at this time), go down.
3. Copy the following blue font to a text file, change its suffix to. Reg, and double-click it to import the Registry. Generally, this problem has been solved. What? Still unable to hear the sound? Haha ~~ Restart the instance.

Conclusion: It was later discovered that this was because the Windows Audio Service was lost, probably because of an abnormal boot operation. In fact, the sound card driver is normal, so don't shut down your server in the future ~~~ Otherwise, the computer may have some inexplicable problems.
