Today, the Windows Home Xiaobian introduces the solution.
First, please confirm that your computer's sound switch or button has been adjusted to the maximum sound. This is a low-level mistake, but there are still many rookies making such mistakes. Check if the sound card, speaker and other devices are connected properly. Left click on the task bar volume icon to see if the click is muted? This is the first step to check the computer for no sound.
2nd, right click "My Computer" - "Properties" - "Hardware" - "Device Manager", open "Sound, Video and Game Controller", see if there is a yellow "?"

In addition, if there is a problem with no sound in the computer or the speaker in the lower right corner is gone, what should I do? We should further check the problem that the computer has no sound according to the following method:
(1) First check the task bar right There is no "small speaker" Internet cafe computer configuration on the side. If there is, the sound card is normal. The cause of the malfunction may be that the system sound is too small, or the mute is set, or the speaker is faulty. You can continue to check for sound output through the headphones, if any, it is a malfunction of the speaker.
(2) If there is no "small speaker" on the right side of the taskbar, then click the "Control Panel /Sounds and Audio Devices" command, open the "Sound and Audio Device Properties" dialog box, and click in this dialog box Click the Sounds tab, then click one of the program events (such as a program error) in the Program Events bar, select a sound category, and see if the Preview button on the right is black. If it is black, the sound card is normal. The cause of the malfunction may be that the system volume is too small, or the mute is set, or the speaker is faulty.
(3) If the "Preview" button in the "Sounds" tab is gray, then click the "Control Panel /System Properties /Hardware /Device Manager" command to see if there is any yellow in the "Device Manager" window The "?" option, with a question mark, will also cause the computer to have no sound.
(4) If there is a yellow "?", see if the option is a sound card device option (the keyword "Audio" or "Sound" is usually included in the sound card device option). If it is an option of the sound card device, it means that the sound card driver is not installed, reinstall the sound card driver, and the silent problem can be solved.
(5) If the option with a yellow "?" does not refer to a sound card device, or if there is no yellow "?" option, then there are no yellow "!" options under the Sound, Video, and Game Controller tabs.
(6) If there is a yellow "!", it may be caused by the sound card driver mismatch or the sound card aging. Then delete the "!" option and reinstall the sound card driver to solve the problem.
(7) If there is no sound card option in the "Device Manager" window, and the sound card is an integrated sound card, then restart the computer and enter the BIOS program (Veryhuo.COM). Then check if the Peripheral option in BiOS is set to "Disabled", and if so, change it to "Enable". If this item is set to "Enable", it may be that the sound card circuit of the motherboard is damaged, and the sound card circuit can be repaired.
(8) If the sound card is not an integrated sound card, then open the case and check if the sound card is installed. If it is not installed, after rebooting, boot the test; if the sound card is already installed, then remove the sound card, and then clean the dust on the motherboard sound card slot and sound card (especially check if the golden finger has mildew, etc.) After cleaning, re-install it, and the general fault can eliminate the computer without sound.
(9) If the sound card is still not working properly, there is a problem with the sound card. Use the replacement method to check if the sound card is damaged or not compatible with the motherboard. If the sound card is damaged or not compatible with the motherboard, replace the sound card.
At this point, I believe that the problem of no sound on the computer can be solved. There is one less worry about why, and everyone will no longer have to worry about the computer with no sound. In fact, summing up 2 points, one is the software driver problem, and the other is the hardware problem. Generally, the sound card is not easy to break, so when we encounter a computer without sound, the first thing that comes to mind is software (such as driver). Try more and sum up, the problem will always be solved.
