Hardware and software together to solve the problem, the computer has no sound problems.

Why is there no sound in the computer? What should I do if the computer has no sound? Computer users often encounter such small problems. The computer has no sound. It is sometimes complicated. It involves both hardware and software issues. Therefore, it is necessary to first find out the cause, whether it is software or hardware failure, and then the right medicine for the problem must not be unclear, it will be irritating, not doing well. Will solve the system, the trouble is big, then everyone follows the Xiaobian from two aspects to analyze this reason:
1. Hardware reasons:
(1) output devices (headphones, speakers, etc.) Poor contact or incorrect settings, check the interface between the device and the computer, re-plug, open the output device switch, and adjust the volume.
(2) Poor sound card contact (the current computer is generally an integrated sound card, here refers to the independent sound card), clean the dust, and then re-plug.

(3) Sound card damage, this situation is very rare, if it appears, it can only replace the sound card, or connect an external sound card (if the integrated graphics card is damaged, you can buy a separate graphics card directly to the PCI plug On the slot).
