The sound card cannot be used out-of-the-box"

1. Check whether the patch cord of the sound card is correct. For example, for a sound card of Apsara stack opti931, there is an implicit jumper jp3 that is not found in the specification. The short circuit is PNP. When the open circuit is opened, Windows 95 cannot recognize the sound card, but the default is open circuit when leaving the factory!

2. What if your sound card is called PNP but Windows 95 does not recognize it? Like the 007 sound card that was difficult to install in the past, the solution is simple: assume that the operating system is dos before installation, first install the audio card driver under DOS and then install Windows 95, select "Sound Card" when the system prompts "Local plug-and-play device" during installation. In autoexec. add "set blster = a220i5d1h5t6" to bat. If this trick is still ineffective, simply reinstall windows3.1, after installing the driver in Windows 3.1 and then upgrading and installing it, Windows 95 will probably recognize the sound card.

3. Try to use new drivers or replacements. Take the lianxun sound card as an example. In Windows95, how can I install the driver on the original drive disk? Instead, I had to replace it with the creative sb16 driver. Everything works normally. Later, I upgraded to Windows 97, but it was not normal. Then I used the built-in audio card driver of Windows 97 (full version. The drivers that come with Windows 98 also do not work. Only the drivers of Windows 97 can play a role.

4. the biggest headache is that the plug-and-play device is detected in Windows 9x, but it does not mean to help you install the driver. This driver cannot be used. In the future, this issue will be repeated every time you delete and reinstall it, and it cannot be solved by "adding new hardware. I disclosed a unique secret here: Enter the win9xinfother directory and put the * about the sound card *. deleting all the INF files and then restarting them, and then manually installing them, this is a hundred percent of the Spirit, and has helped save countless sound card lives ...... Of course, you can also modify the registry for the same purpose.

5. the installation of the PNP sound card is not supported (it is also applicable to the PNP sound card that cannot be installed using the preceding PNP method): Go to the "control panel"/"Add new hardware"/"Next ", when the message "Do I need windows to search for new hardware?" Select "no", and then select "sound, video, and game controller" from the list to use a drive disk or directly select the sound card type for installation.

Sound Card silent

1. The default output of the driver is "mute ". Click the small sound icon in the lower-right corner of the screen to display the volume adjustment slider. The "mute" option is displayed below. Click the check box on the front to clear the check box in the box to pronounce the sound normally.

2. The sound card conflicts with other plug-in cards. The solution is to adjust the system resources used by the PNP card so that each card does not interfere with each other. Sometimes, when "device management" is enabled, although there is no yellow exclamation mark (conflict sign), the sound card does not sound, but there is a conflict, but Windows 95 does not check it out.

3. After DirectX is installed, the sound card cannot be voiced. This indicates that the sound card is not compatible with DirectX and the driver needs to be updated.

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

Sound Card noise is too high

1. The plug-in card is incorrect. The sound card cannot be closely integrated with the expansion slot of the Main Board due to the low-precision chassis manufacturing, sound card bezel manufacturing, or poor installation. Therefore, the "Golden finger" on the sound card is not in place with the expansion slot. This problem occurs on both the ISA card and PCI Card and is a common fault. Generally, pliers can be used for correction.

2. The source speaker input is connected to the speaker output end of the sound card. For an active speaker, it should be connected to the lineout end of the sound card. The output signal does not pass through the power amplifier on the sound card, and the noise is much smaller. Some sound cards have only one output end. The line out or speaker depends on the jumper on the card. The default mode of the manufacturer is usually speaker. Therefore, you need to unplug the sound card and adjust the jumper.

3. Windows 95 (98) driver is not good. When installing the sound card driver, you need to select the "Driver provided by the manufacturer" instead of the "default Windows Driver". If you use the "Add new hardware" Method for installation, select "Install from disk" instead of the list box. If you have installed a driver that comes with windows, you can choose "Control Panel", "system", "device management", and "sound, video, and game controller, select "property"/"driver"/"change driver"/"Install from disk ". Insert the disk or disc attached to the sound card to the driver provided by the manufacturer.

Play CD silently

1. completely silent. With Windows95 "CD player" Put CD silent, but "CD player" and work normally, use a 4-core audio cable to connect the analog audio output of the CD-ROM and the CD-in on the card, this line is included when purchasing CD-ROM.

2. Only one sound channel exists. The optical drive output port generally has two lines of signal, and the two lines in the middle are the ground lines. Because the four colors of the audio signal line are generally different, you can find a one-to-one interface from the line color. If there is only one interface on the sound card or each interface does not match the audio line, you have to change the wiring sequence of the audio line. Generally, only two of the two lines can be swapped.

Abnormal recording

First, check whether the jack is "microphone input". Secondly, double-click the speaker and select "properties"/"Recording" on the menu to check whether the settings are correct. Next, in the control panel/multimedia/devices, adjust the mixer devices and line input devices to the "use" status. If the "Recording" option in "Multimedia"/"audio" is gray, it will be terrible. Of course there is no room for saving, you can try to add "Isa plugandplaybus" in "Add new hardware"/"system device". If not, install the driver in windows3.1. If not, simply install and restart the software of the card-on-board sound card tool.

Cannot play wav, Midi, or CD

It is rare that you cannot play wav music. It is often because there are more than one "audio device" under "Multimedia"/"device". You can disable one; the problem of midi is 16-Bit mode and 32-Bit mode is not compatible with the problem, by installing the software WAVE table should be able to solve; CD silent certainly is because the connection line with the CD-ROM is not good, after the connection is completed.

PCI sound card burst

This is generally because the PCI graphics card uses busmaster technology to increase the background noise during hard disk read/write, mouse movement, and other operations mounted on the PCI bus. Solution: Turn off the bus master function of the PCI video card (but the performance of the video card will be greatly reduced !); Change the PCI sound card to an AGP video card, and change the PCI sound card to a slot.
