1. Insert the wrong hole
Under normal circumstances, as long as the computer sound card is driven correctly, after inserting the speaker, you can play a song, and you can hear the sound. However, some users are not particularly familiar with the jack of the computer sound card, thinking that it can be used normally by simply inserting any hole. This idea is not wrong, but depending on the computer structure and system version, there may be situations where the speaker cannot play the sound. Sound card structure, as shown below:
It should be noted that do not plug the speaker into the front panel of the computer. Although it can also be used, it needs to change the settings. Insert the plug of the data cable into the sound card (light green jack) on the back panel of the computer, and you can hear the sound.
2. Connection error
Taking home audio as an example, generally a subwoofer is used with two-channel small speakers, and the output and input interfaces are divided when connecting.
Under normal circumstances, one end of the data cable connecting the audio will be inserted into the sound card (light green jack) on the rear panel of the computer, the other end will be inserted into the "input" jack of the main speaker, and then the subwoofer and the rest of the small speaker cables will be inserted into In the "out" jack, if it is inserted incorrectly, it will not work properly and no sound will be heard.
3. Audio switch
Many users often make some common sense mistakes. Some speakers are not ready to use after being connected to a power supply. There are one or more switches. The better the speaker, the more switches it has.
If you find that there is no sound from the computer audio, first check whether the audio switch is turned on and whether the power supply is normal. Many users often make some common sense mistakes because of their lack of understanding of audio, which is extremely common in reality.
Digression: In addition, there are some situations that can also cause no sound when the computer is plugged into the speaker, such as sound card damage, audio damage, sound card driver error, wrong computer system default output device settings, etc. For novice users, it is more difficult to set up, test and maintain. It is best to directly find after-sales inspection and maintenance.
Note: Although the text mentions computer audio, it does not involve the hardware model, system version, and software version.
