What are the common causes of computer sound cards?

Common fault one: sound card is silent

Common reasons for this type of failure are:

1. The driver default output is "Mute". Click the small sound icon (small slap) in the lower right corner of the screen, the volume adjustment slider appears, and the “Mute” option is displayed below. Click the check box at the front to clear the checkmark in the box to normal pronunciation.

2. The sound card conflicts with other 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, "Device Management" is turned on. Although the yellow exclamation mark (conflict flag) is not seen, the sound card does not sound. In fact, there is a conflict, but the system does not check it out.

3. The sound card cannot be sounded after Direct X is installed. Note that this sound card is not compatible with Direct X and needs to be updated.

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

Common fault 2: The noise from the sound card is too loud. Common reasons for this type of failure are:

1. The card is not correct. Due to the insufficiency of the manufacturing precision of the chassis and the poor manufacture or poor installation of the sound card outer baffle, the sound card cannot be closely integrated with the main board expansion slot, and the "golden finger" and the extended groove reed on the sound card are visually misaligned. This phenomenon is common on ISA cards or PCI cards and is a common fault. Generally, pliers can be used for correction.

2. The active speaker input is connected to the Speaker output of the sound card. For active speakers, it should be connected to the Line out end of the sound card. The output signal does not pass through the amplifier on the sound card, and the noise is much smaller. Some sound cards only have one output. Line out or Speaker depends on the jumper on the card. The default method of the manufacturer is often Speaker, so you need to unplug the sound card to adjust the jumper.

3. The drivers that come with Windows are not good. When installing the sound card driver, select "provider-supplied driver" instead of selecting

"Windows default driver" If you install with "Add new hardware", select "Install from disk" instead of selecting from the list box. If you have already installed the driver that comes with Windows, select "Control Panel → System → Device Management → Sound, Video and Game Controller", click each device, and select "Properties → Drivers → Change Driver → From Disk. installation". At this time, insert the disk or CD that came with the sound card and load the driver provided by the manufacturer.

Common fault three: the sound card can not be "plug and play"

1. Try to use new drivers or alternative programs. I used to have a sound card. I couldn't install the driver with the original driver in Windows 98. I had to use the Creative SB16 driver instead. Everything is normal. Later upgraded to Windows Me, it is not normal, and then replaced with the sound card driver that comes with Windows 2000 (full version) is normal.

2. The most headache problem is that Windows 9X detects plug-and-play devices but prefers to install drivers for you. This driver is not available. In the future, this will be repeated every time you delete the reload. The problem, and can not be solved by the method of "add new hardware". The author leaked a unique secret trick here: enter the Win9xinfother directory, delete all the *.inf files about the sound card and then manually install it after restarting. This is 100% proof, has saved countless sound card lives... Of course, modify the registration The table can also achieve the same purpose.

3. PnP sound card installation is not supported (also applicable to PnP sound card that cannot be installed with PnP above): Go to "Control Panel" / "Add New Hardware" / "Next", when prompted "Do you need Windows to search for new hardware? When you select "No", then select "Sound, Video, and Game Controller" from the list to install it with the drive disk or directly select the sound card type.

Common fault four: playing CD silent

1. Completely silent. Using the "CD player" of Windows 98 to put the CD silent, but the "CD player" works fine again, which means that the audio cable of the optical drive is not connected. Use a 4-pin 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 purchase of the CD-ROM.

2. Only one channel is sounding. The optical drive output port generally has two left and right signals, and the middle two lines are ground. Since the four lines of the audio signal line are generally different in color, a one-to-one correspondence 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 the wires are swapped.

Common fault five: PCI sound card popping

Generally, the PCI graphics card uses the Bus Master technology to amplify the background noise caused by hard disk read/write and mouse movement on the PCI bus. Solution: Turn off the Bus Master function of the PCI graphics card, replace it with the AGP graphics card, and replace the PCI sound card with the slot.

Common fault six: unable to record properly

First check if the microphone is plugged into the other jacks. Secondly, double-click the small speaker and select “Properties→Record” on the menu to see if the settings are correct. Next, adjust "Mixer Device" and "Line Input Device" in "Control Panel → Multimedia → Device" and set them to "Use" status. If the "Recording" option in "Multimedia→Audio" is gray, it is not bad. Of course, there is no room for saving. You can try adding "ISA Plug and Play bus" in "Add New Hardware→System Device". , simply restart the sound card with the card tool software installed.

Common fault seven: Can't play Wav music, Midi music

It is rare to play Wav music. It is often because there is more than one "audio device" under "Multimedia" → "Device". One can be disabled. There are three possibilities for not playing MIDI files:

1. The early ISA sound card may be caused by the incompatibility of 16-bit mode and 32-bit mode, which may be solved by installing the software wave table.

2. Most popular PCI sound cards today use wavetable synthesis technology. If the MIDI part cannot be played, it is likely that you have not loaded the appropriate wavetable sound library.

3. The MIDI channel in the Windows volume control is set to silent mode.

Common fault eight: PCI sound card is not working properly under WIN9 8

Some users have reported that everything is normal during the sound card driver installation process, and there is no device conflict, but there is no sound or other faults under WIN98. This phenomenon usually occurs on the PCI sound card. Please check which PCI slot you inserted the PCI sound card during the installation. Some friends like to put the sound card in the PCI slots away from the AGP slot and close to the ISA slot for heat dissipation reasons. The problem often comes up here because Windows 98 has a bug: sometimes it only correctly recognizes the sound card inserted in the PCI-1 and PCI-2 slots. The two PCIs on the ATX motherboard that are close to AGP are PCI-1 and PCI-2 (the opposite is true on some ATX motherboards, PCI-1 is close to ISA), so if the PCI sound card is not installed correctly. On the slot, the problem will arise.
