The sound card conflicts 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 the "Device Manager", although there is no yellow exclamation point (conflict flag), but the sound card is not sounding, in fact, there are conflicts, but the system does not detect it. After installing DirectX, the sound card cannot be audible, indicating that the sound card is not compatible with DirectX and needs to update the driver.

If there is no sound in one channel, check if the audio cable from the sound card to the speaker is disconnected.

sound excessive noise may be caused by several reasons:
a, the card is not correct, the sound card is not tightly integrated with the motherboard expansion slot, visually visible sound card There is a misalignment between the "Golden Finger" and the extended groove spring. This phenomenon is common on ISA cards or PCI cards. It is a common fault. If you want to make the sound card plugged in, you can solve the problem.

b, the active speaker input is connected the output of the sound card Speaker, active speaker should be connected to the sound card Line-Out, it outputs a signal on the card has not been amplified, noise is much smaller many. Some sound cards only have one output. Line-Out or Speaker depends on the jumper on the card.
