In order to solve this problem, this article will share some possible useful solutions. 1. Check whether the speaker is turned on. When using the speaker on the computer, first make sure that it is correctly connected to the computer and turned on. Usually, the speaker is connected to the audio output port of the computer. If you are not sure whether the speaker is turned on, you can refer to the speaker's guide to turn on the power and adjust the volume. Two. Check whether the volume is muted. Sometimes in the process of using the computer, we will accidentally adjust the volume to mute, so the speaker will not make a sound.If the computer uses a multimedia keyboard or volume control button, please make sure that the volume has been restored to normal. If there is no control button, you can check whether the volume is muted by clicking the volume icon in the lower right corner of the desktop taskbar. If the mute is turned on, clicking the icon will open the volume adjustment tool for you and bring the volume back to normal. 3. Check the audio settings. When the first two methods are ineffective, it is recommended to check the audio settings of the computer. To do this, press the Win+R key, enter "mmsys.cpl", and then click the "OK" button to open the sound option. Here, you can check which audio device your computer is using. If you have connected an external speaker, you should select the speaker as the default audio device of the computer. If the external speaker is not the default device, right-click the device and select the "Set as Default Device" option.Four. Check the driver. If your computer still can't make a sound, you should check whether you need to update the driver. In the Win7 system, find the problematic audio device and right-click to view its properties. In the "Properties" dialog box, find the "Driver" tab, and then click the "Driver Update" button. At this time, the system will automatically check whether the device driver needs to be updated. If it has expired or is invalid, you can download and install the latest driver through Microsoft's official website. 5. Restart the computer. Sometimes, the easiest way to get a problem with the computer is to restart it. This method may seem simple, but it can be very effective for simple problems such as the speaker's inability to make a sound. After resetting the system, it may automatically solve some problems and make the system run more smoothly.Summary By using the above solutions, the speaker problems of most Win7 systems can be solved. If you are using a Win7 system and the speaker cannot make sound, you can try the above method. Of course, although these methods may be effective, different computer problems are also different.
