In the newly upgraded win10 system, what should I do if the video has no sound ?, Win10 video

I just changed the win10 system and was not very familiar with it. I just wanted to watch the video but found no sound. Why? Let's take a look.

As usual, the new system should be a driver problem. Go to the system properties page and click device management,

Go to the device management option, observe the sound, video, and game controller options, and check whether the Yellow Triangle sign is displayed. If it appears, it indicates that the driver is abnormal and you need to reinstall the driver, update with third-party Driver Management Software

After the driver works properly, right-click the Sound horn icon in the taskbar and select "Play Device" in the pop-up menu"

For the newly installed win10 system, the default device is Headphone, which means the headset (via hd Audio Sound Card and Realtek audio sound card only display a little different ), win10 is a headset by default (strange). Of course there will be no sound on the speaker.

Select the speaker, right-click the speaker, and set the speaker to the default device. That is, enable the computer speaker as the audio output preference, so there should be sound.

For better sound effects, you can right-click and select Properties, switch to "add function", and enable an enhancement effect you like to achieve better sound quality!
