The computer speakers do not sound, which troubles many users. PHP editor Youzi brings you a solution. The following will introduce in detail how to set up computer speakers to make your computer produce beautiful sounds.
Right-click the sound icon, select Troubleshoot Sound Problems, select the default sound device, turn on the audio enhancement function, switch to the level options bar, enlarge the sound adjuster, turn on the volume synthesizer, and turn off all sounds
The subwoofer of the computer speaker does not sound. This is caused by the wrong audio plug.
The subwoofer of the computer speaker should be plugged into the pink audio interface on the back of the computer to output the bass signal correctly. If it is plugged in incorrectly, it will cause The subwoofer doesn’t sound
If it is convenient, you can use a multimeter to test and check step by step:
1. To test the tweeter unit, use the minimum resistance setting. If the speaker is intact, the resistance value is close to zero, and the speaker has an obvious response;
2. Test the connection Make sure there are no breakpoints in the connecting wire;
3. Pay attention to a problem. If your tweeter is connected to the power amplifier, if you use a snap wire, you must pay attention to ensure good contact.
4. As you said, it is judged that there is a problem with your power amplifier circuit. From the simplest check, you can measure whether the volume adjustment is normal, whether there are any solder joints on the power amplifier circuit board, etc. If it is determined that there is a problem with the power amplifier circuit, It is recommended to send it for repair.
5. Before simply testing the speakers, you must confirm that the computer audio output signal is normal. You can use headphones to test it. Good luck!
The desktop sound jack is divided into two jacks: front and rear. The rear jack is the main output jack of the sound card. The default sound output of the computer is the rear jack. The front sound jack is from the motherboard through the front small board. The adapter board contains a sound socket and two USB sockets. If you want to output sound from the front socket, you need to set the front interface option in the sound card settings. This allows sound output from the front panel.
There are several reasons why the subwoofer of the stereo does not sound.
It may be that the subwoofer of the stereo is broken and the speaker needs to be replaced.
Maybe the amplifier of the subwoofer is broken and needs to be repaired before it can be used normally.
There may also be a problem with the audio connection cable or it is not connected properly.
It is recommended to change the sound source (such as MP3, etc.), or get another computer to audition the sound. The first thing to eliminate is the fault of the speaker. You can choose music with obvious heavy bass. If it still doesn't sound, and only two small speakers sound, it shouldn't be a problem with the power amplifier circuit in the subwoofer. There should be a problem with your bass unit, and it's best to get it repaired.
1. If it was normal before but abnormal later, you can rule out the problem with your wiring. However, audio hardware problems and setting problems cannot be ruled out. Hardware problem: You can only test it with other people's small speakers to see if your own really has no sound. Setting problems: Click the sound icon in the lower right corner of the taskbar to see if there is any problem with the settings. The drivers of each type of speakers are different, so the setting interface is also different. It is difficult to give specific setting methods here. But as long as options such as "Mute" are not checked, the sound can generally be made.
2. Are you really sure you didn’t connect the wrong line? Do you want to reconfirm?
3. How do you confirm that "the big speaker has sound and the two small speakers have no sound"? Is it verified by a song? What I mean is that some audio sources only have one channel.
It seems simple to have a silent computer, but sometimes the problem is more complicated, involving both hardware and software issues. Therefore, we must first find out the cause, whether it is software or hardware failure, and then prescribe the right medicine for the problem. 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/Sounds and Audio Devices" command to open the "Sounds and Audio Device Properties" dialog box, and click "Sound" in this dialog box " tab, 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 and check whether there is a yellow "?" in the "Device Manager" window. options.
4. If there is a yellow "?", check whether the option is a sound card device option (the sound card device option usually has 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 the yellow "?" option does not refer to the sound card device, or there is no yellow "?" option, then check whether there is a yellow "!" option under the sound, video and game controller tabs.
6. If there is a yellow "!", it may be caused by a mismatched sound card driver or an aging sound card. Then delete the option with "!" and 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.
10. Download the sound card driver. It is recommended to use Driver Wizard to download drivers compatible with the sound card.

不能。这种是3芯插头，插头上几个环状触点的位置跟电脑音频输出插座内部的触点簧片位置错位，所以没有信号输出。
不响的主要原因是喇叭开关内部的触点接触不好导致的，当然也有喇叭本身故障的可能性。首先检查熔丝看是否熔断，然后拔下喇叭插头，用万用表测量在按喇叭开关时此处是否有电。
如果没有电，应检查喇叭线束和喇叭继电器；如果有电，则是喇叭本身出现故障，此时也可以试着调节喇叭上的调节螺母看是否能发声，如果还是不响，则需要更换喇叭。
