This article is to share with you about how to solve the problem of computer sound card failure. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Common fault one: the sound card is silent.

The common reasons for this failure are:

1. The default output of the driver is "mute". Click the small sound icon (small gargle) in the lower right corner of the screen, the volume adjustment slider appears, and there is a "mute" option below. Click the check box in front and clear the check mark in the box to pronounce normally.

2. there is a conflict between the sound card and other cards. The solution is to adjust the system resources used by PNP cards so that they do not interfere with each other. Sometimes, open "device Management", although there is no yellow exclamation mark (conflict sign), but the sound card is silent, in fact, there is a conflict, but the system is not checked out.

3. The sound card cannot produce sound after installing Direct X. This indicates that this sound card is not compatible with Direct X and the driver needs to be updated.

4. One channel is silent. Check if the audio cable from the sound card to the speaker is disconnected.

Common failure 2: the noise emitted by the sound card is too loud

The common reasons for this failure are:

1. The card is not inserted correctly. Due to the low manufacturing precision of the chassis and the poor manufacture or installation of the sound card outer bezel, the sound card can not be closely combined with the expansion slot of the motherboard, and it can be seen that there is a dislocation between the "golden finger" and the expansion slot spring on the sound card. This phenomenon exists on both ISA and PCI cards and is a common fault. Generally, it can be corrected with pliers.

2. The active speaker input is connected to the Speaker output of the sound card. For the active speaker, it should be connected to the Line out end of the sound card, and its output signal does not pass through the power amplifier on the sound card, so the noise is much less. Some sound cards have only one output, and whether Line out or Speaker depends on the jumper on the card. The manufacturer's default mode is often Speaker, so unplug the sound card to adjust the jumper.

3. The driver included in Windows is not good. When installing the sound card driver, select "manufacturer-supplied driver" instead of "Windows default driver". If you install it with "add new hardware", select "install from disk" instead of selecting from the list box. If you have installed the driver that comes with Windows, you can choose "Control Panel → system → device Management → Sound, Video and Game Controller", click on each device, and select "Properties → driver → change driver → installed from disk". At this point, insert the disk or CD attached to the sound card and install the driver provided by the manufacturer.

Common failure 3: the sound card cannot be "plug and play".

1. Try to use new drivers or replacements. The author once had a sound card, which could not be installed with the original driver disk under Windows 98, so it had to be replaced by Creative SB16 driver, and everything was normal. Later, when I upgraded to Windows Me, it was not normal to switch to the sound card driver that comes with Windows 2000 (full version).

2, the biggest headache is the plug and play device detected under Windows 9X but decided to help you install the driver, this driver can not be used, in the future, every time you delete the reinstallation will repeat this problem, and can not be solved by "adding new hardware". The author here reveals a secret trick: enter the Win9xinfother directory, delete all the * .inf files about the sound card and then restart it and install it manually, which is 100% effective and has saved the lives of countless sound cards. Of course, modifying the registry can also achieve the same goal.

3. Do not support the installation of PnP sound cards (also applicable to PnP sound cards that cannot be installed with the above PnP method): go to "Control Panel" / "add New hardware" / "next step" when prompted "do you need Windows to search for new hardware?" Select "No", and then select "Sound, Video and Game Controller" from the list to install with the drive or directly select the sound card type.

Common malfunction 4: playing CD is silent

1. Completely silent. Play the CD silently with the "CD player" of Windows 98, but the "CD player" works normally, which means that the audio cable of the CD-ROM drive is not connected properly. Use a 4-core audio cable to connect the analog audio output of the CD-ROM to the CD-in on the sound card, which is included with the CD-ROM purchase.

2. Only one sound channel makes a sound. Optical drive output generally left and right two lines of signal, the middle two lines for the ground wire. Because the colors of the four lines of the audio signal line are generally different, the one-to-one corresponding interface can be found from the color of the line. If there is only one interface on the sound card or each interface does not match the audio cable, you have to change the wiring order of the audio cable, usually only two of them can be swapped.
