The reason why the computer sound is very small, Common faults of sound cards and speakers are mainly silent, low sound, only one speaker has sound, the sound changes pitch, there are popping sounds, there are crackling sounds, etc., which cause this fault The main reasons include mute, too low volume, sound card driver problems, damaged speakers, damaged sound card modules, BIOS setting problems, conflicts between the sound card and other devices, poor sound card contact, damaged sound cards, etc.
The troubleshooting method for computer silence is as follows:
(1) First check whether there is a "small speaker" on the right side of the taskbar. If so, the sound card is normal. The cause of the fault may be that the system sound is too low, or mute is set, or the speaker is faulty. You can continue to check whether there is sound output through the headphones. If there is, the speaker is faulty.
(2) If there is no "Small Speaker" on the right side of the taskbar, then click the "Control Panel/Sound and Audio Devices" command to open the "Sound and Audio Device Properties" dialog box, and open the dialog box Click the "Sound" tab in the box, then click one of the program events (such as a program error) in the "Program Events" column, then select a sound type, and then see if the "Preview" button on the right is black. If it is black, the sound card is normal. The cause of the fault may be that the system volume is too low, or mute is set, or the speaker is faulty.
(3) If the "Preview" button in the "Sound" tab is gray, then click the "Control Panel/System Properties/Hardware/Device Manager" command to view the "Device Manager" window Is there a yellow "?" option?
(4) If there is a yellow "?", check whether the option is a sound card device option (the sound card device option usually contains keywords such as "Audio" or "Sound"). If it is an option for the sound card device, it means that the sound card driver is not installed. Reinstall the sound card driver and the silent problem will be solved.
(5) If there is a yellow "?" option that does not refer to the sound card device, or there is no yellow "?" option, then check whether there is a yellow "!" under the sound, video and game controller tabs. options.
(6) If there is a yellow "!", it may be caused by a mismatched sound card driver or an aging sound card. Then delete the tags with “!” option, just reinstall the sound card driver.
(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. Then check whether the peripheral device option in the BIOS is set to "Disabled", if so, change it to "Enable". If this item is set to "Enable", the motherboard sound card circuit may be 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 whether the sound card is installed properly. If it is not installed, just reinstall it and start the test; if the sound card has been installed, then remove the sound card, and then clean the motherboard sound card slot and the dust on the sound card (especially check whether the gold finger has mold spots, etc.). After cleaning and reinstalling, general faults can be eliminated.
(9) If the sound card is still not normal, there is a problem with the sound card. Use the replacement method to check whether the sound card is damaged or incompatible with the motherboard. If the sound card is damaged or incompatible with the motherboard, just replace the sound card.
