The sound card is the hardware part of the computer control core processing audio output, which is divided into a sound card and an independent sound card. Sound card hardware is generally not prone to problems, most of the time software problems occur. The following system home Xiaobian will tell you how to fix these common sound card failures. First, the storm problem is the most common sound card problem, here we first come to understand the cause of the storm. 1, the sound card and chipset conflict This kind of failure usually occurs when the new sound card is equipped with the old motherboard. For example, when the innovation releases the Audigy chip sound card, it is not compatible with the VIA motherboard, there is a problem of sound and even sound skipping. These faults can be Solve by updating the motherboard Bios or upgrading the sound card driver. 2, IDE settings problems Some friends often encounter such problems, when playing a DVD through the optical drive, you will find that the sound of the sound is more serious, and when copying the file to the hard disk, there is no sound. At this time, the optical drive may be in PIO mode, and it can be changed to DMA mode. Modify the working mode of the optical drive 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. 3, the power failure 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. 4, PCI devices compete for bandwidth When the CPU load is heavy or a large amount of data replication is in progress, there is a storm, which is caused by the sound card driver execution level is too low to compete with other devices for bandwidth. Generally, the 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. Second, no sound failure Sometimes, the sound card can be identified, but also can successfully install the driver, but it is impossible to voice, view device resources, showing no resources available or resource conflicts, resulting in equipment is not available. This situation is mostly 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. Third, the installation of multiple sound cards in a system to install multiple sound cards is very easy to problems, especially when using the same audio accelerator. The most conflicting place for sound card installation is the game port. They are often assigned to the same resource, easily blue screen at startup, or one of them cannot be used. At this time, one of them should be disabled. Since some drivers have very similar file structures, which are modified from the public version of the driver, some sound cards cannot work together. This is because the system cannot correctly assign resources to the sound card, and the replacement of the operating system should be solved. Fourth, Windows Server2003 installed the old sound card Server2003 is Microsoft's latest server operating system, this system from the test version began to give up support for all ISA devices and old PCI devices, including the classic AWE64 Gold sound card, AWE64 Gold Server2003 is just a yellow exclamation point, but this does not mean that AWE64 Gold can't work on Server2003. In addition, in order to save resources, Server2003 does not allow the sound card to sound by default, even if you have the driver installed correctly. In Windows 2003 there is a service called Windows Audio, the default startup state is forbidden, changed to automatic mode, and then restarted. V. Noise Problems Some friends often complain that their sound card is noisy. This may be because other device channels on the sound card are not muted. Open the mixer that comes with Windows. Turn off all channels except the one you are using, which will result in good sound quality, especially for some sound cards with some PCB design defects. 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. Sixth, 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 audio card multi-audio stream support is not good, you can install Microsoft's WDM driver. solve. 7. DirectSound Delay Some sound card processing capabilities are not very powerful. When running at full load, the playback of DirectSound audio stream may be delayed or some basic DirectSound sound effects should be given to the CPU for calculation, which will reduce the efficiency of the program. In the Run dialog, type: DxDiag and execute. Pull the Full acceleration slider to the far right to enable the full acceleration of the sound card's main DSP chip.
