First, the storm is the most common sound card problem, the following analysis of the reasons for the storm.
1. Problems with IDE settings
Some friends will encounter a serious sound when playing a DVD through a CD-ROM drive. When copying files to the hard disk, there will be no sound, then this time The CD-ROM drive may be in PIO mode, it can be changed to DMA mode, and the working mode of the CD-ROM drive is modified in the control panel hardware manager. If the problem cannot be solved after setting it, it may be that the motherboard chipset driver needs to be updated.
2, the power supply is faulty
The sound card is a device that is sensitive to the power supply, so a good PC power supply can help improve the sound quality. In the case of poor quality power supply, there may be frequent sounds, especially those with a power amplifier circuit. A small fluctuation of the power supply will cause noise or even a violent sound. In this case, only the power supply or sound card is replaced.
3, PCI devices compete for bandwidth
When the CPU load is heavy or a large amount of data is being copied, there is a sound, which is caused by the sound card driver execution level is too low to compete with other devices for bandwidth, general situation The lower sound card manufacturer does this in order to obtain the stability of the system. This situation is very easy to happen when using PCI graphics cards, this is because PCI devices compete for bandwidth.
4, may be the sound card and chipset conflict
This kind of failure usually occurs when the new sound card is equipped with the old motherboard, such as the innovation release of the Audigy chip sound card, and the VIA motherboard is not in line, there is a violent sound or even appear For the problem of skipping, these faults can be solved by updating the motherboard Bios or upgrading the sound card driver.
Second, the noise problem
This problem may be caused by the other device channel on the sound card is not muted, you can open the mixer that comes with Windows, and then close all channels except the channel you are using, This will bring a good sound quality improvement, especially for some sound cards with some defects in PCB design. In addition, some noise is caused by poor anti-interference of the sound card itself, and the host is not connected to the ground. At this time, the PC should be grounded, so that the computer will be safer.
Three, no sound failure
Sometimes, the sound card can be identified, but also can successfully install the driver, but it does not happen, when viewing the device resources, there is no resource available or resource conflict, resulting in the device is not available, Most of the cases are caused by the contention of the network card. The order of rearranging the PCI slots can be solved. If the resource conflicts are displayed, you can also try to allocate resources manually.
Fourth, the installation of multi-sound card caused the sound card failure
When installing multiple sound cards in the Ghost win7 system is very easy to have problems, especially when using the same audio accelerator, the most likely conflict between the sound card installation is the game port, They are often assigned to the same resources, easily blue screen at startup, or one of them can not be used, this time should be banned, because some of the driver's file structure is very similar, all from the public version of the driver modified, so Some sound cards are not working together. This is because the system cannot correctly assign resources to the sound card, and reinstalling or replacing the operating system should solve the problem.
5, DirectSound delay
Some sound card processing power is not very powerful, in the case of non-full load operation, playback of DirectSound audio stream may appear delayed or some basic DirectSound sound effects should be given to the CPU to calculate, this will Reduce the running efficiency of the program. Solution: Enter: DxDiag in the running dialog box, then press Enter to pull the Full acceleration slider to the far right, which can enable the full acceleration capability of the main DSP chip of the sound card. .
Six, can not play multi-audio stream
When using some old sound card under Windows98, you will find that when playing music, other sounds will not be sent out. This is because the sound card does not support audio stream well. Install Microsoft's WDM driver to solve it.
