No sound from the computer is one of the common problems in the use of computers. This article focuses on the seven common problems of computer sound cards and the troubleshooting methods.
First, the violent problem
The violent sound is the most common sound card problem, here we first understand the reasons for the violent sound.
1. Conflict between sound card and chipset
This kind of failure usually occurs when the new sound card is equipped with the old motherboard. For example, when the Audigy chip sound card is innovatively released, it is inconsistent with the VIA motherboard, and there is a problem of violent noise or even sound skip. Drive to solve.
2. Problems with IDE settings
Some friends often encounter this kind of problem. When playing a DVD through an optical drive, they will find that the sound is loud, but when the files are copied to the hard disk to play, there is no loud sound. At this time, the optical drive may be out of PIO mode, just change 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 may be that the motherboard chipset driver needs to be updated.
3. Power failure
The sound card is a device that is more sensitive to power, so a good PC power supply will help improve the sound quality. When paired with inferior power supplies, violent noise may often occur, especially for sound cards with power amplifier circuits. A small fluctuation in the power supply will cause noise or violent noise. In this case, only the power supply or sound card has been replaced.
4. PCI devices compete for bandwidth
When the CPU load is heavy or a large amount of data is being copied, there is a loud noise. This is caused by the sound card driver's execution level being too low to compete with other devices for bandwidth. Generally, sound card manufacturers do this to achieve system stability. Sex. This situation is very likely to occur when using PCI graphics cards, which is caused by PCI devices competing for bandwidth.
Second, no sound failure
Sometimes, the sound card can be recognized and the driver can be installed smoothly, but even if the sound cannot be heard, viewing the device resources shows that no resources are available or resource conflicts, causing the device to be unavailable. This situation is mostly caused by contention with the network card. Rearranging the order of the PCI slots can be solved. If resource conflicts are displayed, you can also try to allocate resources manually.
Third, install multiple sound cards
Installing multiple sound cards in a system is prone 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 resources. It is easy to get a blue screen when starting up, or one of them cannot be used. At this time, one of them should be banned. Because the file structure of some drivers is very similar, all of which are modified from the public version of the driver, so some sound cards cannot work together. This is because the system cannot correctly assign resources to the sound card, and replacing the operating system should solve it.
Fourth, install the old sound card under Windows Server2003
Server2003 is Microsoft's latest server operating system. This system has abandoned support for all ISA devices and old PCI devices since the beta version, including the classic AWE64 Gold sound card. AWE64 Gold is just a yellow exclamation mark under Server2003, but This does not mean that AWE64 Gold cannot work on Server2003. In addition, in order to save resources, Server2003 can not make the sound card sound by default, even if you install the driver correctly. In Windows 2003, there is a service called Windows Audio. The default startup state is disabled, change to automatic mode, and then restart.
5. Noise
Some friends often complain that their sound card is noisy. This may be because the channels of other devices on the sound card are not muted. Open the mixer that comes with Windows. Turn off all channels except those in use, which will bring good sound quality improvement, especially for some sound cards that have certain defects in PCB design. In addition, some noise is caused by the sound card's poor anti-interference, plus the host is not connected to the ground wire, then the PC should be grounded, so that the computer will be safer.
Six, unable to play multiple audio streams
When using some old sound cards under Windows98, you will find that when playing music, other sounds can not be output, this is because the sound card multi-audio streaming support is not good, you can solve it by installing the Microsoft WDM driver.
Seven, DirectSound delay
Some sound cards are not very powerful in their own processing. When running under full load, the playback of the DirectSound audio stream may be delayed or some basic DirectSound sound effects must be handed over to the CPU to calculate, which will reduce the efficiency of the program. Enter: DxDiag in the run dialog box and execute. Pull the Full acceleraTIon (hardware acceleration) slider to the far right, so that you can enable all the acceleration capabilities of the main DSP chip of the sound card.
