1. What should I do if my computer has no sound?

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 yes, 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 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 mismatch of the sound card driver or aging of the 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 properly, 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 the gold finger Whether there are mold spots, etc.), clean and reinstall it, and 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) Sound card driver download /drivers.

8. The computer has no sound, how to fix it?

We often encounter the phenomenon that the sound card cannot produce sound or the sound is abnormal.

How to troubleshoot and make the sound card produce beautiful sound? 1. The sound card is silent. The system default sound output is "silent". Click the small sound icon (small speaker) in the lower right corner of the screen, a volume adjustment slider will appear, and there is a "Mute" option below. Click the check box in front of it, clear the check mark in the box, and you can pronounce normally.

The sound card conflicts with other plug-in cards. The solution is to adjust the system resources used by the PnP card so that the cards do not interfere with each other.

Sometimes, when you open the "Device Manager", although there is no yellow exclamation point (conflict mark), the sound card just does not make any sound. In fact, there is a conflict, but the system has not detected it. If the sound card cannot produce sound after DirectX is installed, it means that the sound card is not compatible with DirectX and the driver needs to be updated.

If one channel is silent, check whether the audio cable from the sound card to the speaker is broken. 2. Playing the CD without sound. In the case of complete silence, use the Windows 98 CD player to play the CD without sound, but the CD player works normally.

At this time, just use a 4-core audio cable to connect the analog audio output of the CD-ROM and the CD-In on the sound card. This cable will be provided when purchasing the CD-ROM drive. For situations where there is only one channel of sound, the optical drive output port generally has two left and right signal lines, and the two middle lines are ground wires.

Since the colors of the four audio signal cables are generally different, you can find the one-to-one corresponding interface from the color of the audio cable. At this time, it may be that the interface on the sound card does not match the audio cable. Just change their positions and make them match.

3. Unable to play WAV, MIDI or CD music. The inability to play WAV music is often due to the fact that there is more than one "audio device" under "Multimedia" → "Device". In this case, just disable one; MIDI problem It is caused by the incompatibility between 16-bit mode and 32-bit mode, which can be solved by installing software wave table. The reason why the CD is silent must be because the connection cable to the CD-ROM drive is not connected properly. After the connection, there should be no problem. 4. Excessive sound card noise may be caused by the following reasons: a. The card is not inserted correctly, and the sound card is not tightly integrated with the expansion slot of the motherboard. It can be seen visually that the "golden finger" on the sound card is misaligned with the reed of the expansion slot.

This phenomenon occurs on ISA cards or PCI cards. It is a common fault. You can solve the problem by plugging the sound card correctly. b. The input terminal of the active speaker is connected to the Speaker output terminal of the sound card. The active speaker should be connected to the Line-Out terminal of the sound card. The signal it outputs is not amplified by the sound card, and the noise is much smaller.

Some sound cards have only one output. Whether it is Line-Out or Speaker depends on the jumper on the card. The default mode is often Speaker, so if necessary, you have to unplug the sound card to adjust the jumper. c. The version of the installed sound card driver is not good. You may be using the driver that comes with the system. If so, it is best to install a special sound card driver.

If you have installed the driver that comes with Windows, select "Control Panel → System → Device Manager → Sound, Video, and Game Controllers", click on each device, and select "Properties → Driver Programs → Change Driver → Have Disk”. At this time, insert the disk or CD that came with the sound card and install the driver provided by the manufacturer.
