The common breakdown of sound card in rain forest wind Win7 system and the solving method

One, the most common sound card problems, the following analysis of the cause of the sound.

1, the IDE set the problem

Some friends will encounter a DVD in the optical drive, will find that sound is more serious, and the file copied to the hard disk playback, there is no beep, then the CD-ROM may be out of PIO mode, changed to DMA mode, modify the operating mode of the optical drive in the Control Panel hardware controller. If the problem is not resolved after Setup, the motherboard chipset driver may need to be updated.

2, power failure

A sound card is a more sensitive device to the power supply, so a good PC power supply is helpful for improving sound quality. In combination with inferior power supply, may often appear the phenomenon of sound, especially those with power amplifier circuit sound card, power a little bit of fluctuations will cause noise and even sound, this situation will only replace the power or sound card.

3, PCI equipment contention for bandwidth

When the CPU load is large or a large number of data replication, there is a beep, this is the sound card driver execution level is too low to compete with other devices for bandwidth caused by, in general, the sound card manufacturers to achieve the stability of the system. This happens very easily when using a PCI video card because the PCI device is competing for bandwidth.

4, may be a sound card and chipset conflict

This failure usually occurs when the new sound card with the old motherboard, such as the innovative release of the Audigy chip sound card, and via the motherboard is inconsistent, there is a beep or even the problem of skipping, these failures can be updated motherboard BIOS or upgrade the sound card driver to solve.

Second, the noise problem

The problem may be that the other device channels on your sound card are not muted, you can open windows with the mixer, and then close all the channels outside the channel you are using, this will bring good quality improvement, especially for some PCB design has a certain flaw in the sound card. In addition, there are some noise is the sound card itself caused by poor anti-interference, plus the host and did not access the ground, this should let the PC grounding, so the computer will be more secure.

Third, the failure of sound

There are times when sound card can be recognized, but also can successfully install the driver, but it will not happen, view the device resources when the display is not available resources or resource conflicts, resulting in the device is not available, this situation is mostly and network card contention address, rearrange the sequence of PCI slots can be resolved, if the display of resource conflicts You can also try to allocate resources manually.

Four, the installation of multiple sound card causes sound card failure

When installing multiple sound cards in a ghost Win7 system is very easy to issue, especially when using the same audio accelerator, the sound card installation of the most easily conflict place is the game port, they are often assigned to the same resources, at the start of the easy blue screen, or one of the unusable, This time should be banned one, because some of the driver's file structure is very similar, from the public version of the driver to change, so some sound cards can not work together. This is because the system does not properly assign resources to the sound card, and reinstalling or replacing the operating system should be able to resolve the problem.

V. DirectSound delay

Some sound card itself processing power is not very strong, when not full load operation, playback DirectSound audio stream may be delayed phenomenon or some basic DirectSound sound effects to the CPU to operate, this will reduce the efficiency of the program, the solution: In the Run dialog box input: D Xdiag, then enter execution, the full acceleration (Hardware acceleration) slider to the right, so that you can enable the sound card main DSP chip all the acceleration capability.

Six, unable to play multiple audio streams

When you use some old sound cards under Windows98, you will find that when you play the music, other sounds will not come out, this is because the sound card multiple audio streaming support is not good, you can install Microsoft's WDM drive to solve.
