The computer motherboard integrates a sound card, and the Windows system is installed. It used to be normal, but recently, when playing music files on CD or hard disk, I found that only one speaker had sound - that is, only one channel had sound. This is still the case after changing a pair of speakers, while there is no problem with the motherboard and sound card.
This situation may be caused by the wrong setting of the "Wave" in the volume control, or a problem with the driver installation. First, double-click the small speaker icon in the desktop task tray to open the "Master Volume" dialog box, and check whether the "Balance" slider in the "Wave" is dragged to one side; if it is, drag it to the center and try if the speaker is normal; in addition, Windows will automatically install drivers for each hardware, but sometimes these installed drivers are not compatible with motherboards and other accessories. In this case, you need to uninstall the original driver, and then reinstall or download the latest driver for the upgraded sound card program. The speaker should be able to sound normally.
