What if there's no sound after the computer reload the system?

Often encounter a sound card can not voice or abnormal sound phenomenon. How to troubleshoot, so that sound card issued a beautiful sound?

1, sound card silent

The system default sound output is mute. Click on the lower right corner of the sound small icon (small horn), the volume adjustment slider, there is a "mute" option, click the Front of the check box, clear the box tick, you can pronounce correctly.

The sound card is in conflict 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, open "Device Manager", although no yellow exclamation point (conflict flag), but the sound card is not audible, in fact, there is conflict, but the system is not detected just. The sound card does not sound when you install DirectX, which means that the sound card is not compatible with DirectX and needs to be updated with the driver.

If it is a sound track, then check the audio card to the speaker line is disconnected.

2, Play CD silent

In the case of utter silence, CD player with Windows 98 is silent, but the CD player works fine. A 4-conductor audio line is used to connect the analog audio output of the CD-ROM with the cd-in on the sound card, which is provided when the CD-ROM drive is purchased.

For only one sound channel, the optical drive output is generally left and right two lines of signal, the middle two lines for the ground. Because the 4-line color of the audio signal line is generally different, you can find one by one corresponding interfaces from the color of the audio line. It is possible that the interface on the sound card does not match the audio line, swap their position, let it match on the line.

3, unable to play WAV, MIDI or CD music

Can not play WAV music is often due to "multimedia" → "equipment" under the "audio device" more than one, then disable a can; The problem with MIDI is that the 16-bit mode is incompatible with the 32-bit mode and can be solved by installing the software Wave table; The CD must be silent because the cable to the CD-ROM drive is not connected properly and there should be no problem after that.

4, sound card noise too large

This may be due to several reasons:

A, card is not, the sound card is not with the motherboard expansion slot closely combined, through visual visible sound card on the "golden Finger" and expansion groove reed dislocation phenomenon. This phenomenon in the ISA card or PCI card, is a common fault, to find a way to plug the sound card can solve the problem.

b, the active speaker input is connected to the speaker output of the sound card, the active speaker Bell in the sound card line-out end, it output signal did not go through the sound card amplification, noise is much smaller. Some sound card only one output, is line-out or speaker to rely on the jumper on the card, the default way is often speaker, so if necessary, unplug the sound card adjustment jumper.
