① The high-definition audio bus on the computer (high-definition audio bus is a basic platform and a program) and Realtek high-definition audio (the driver of Ruiyu sound card). Ruiyu produces sound cards) These two programs are normal-you can see from the picture on the device manager you uploaded.

(2) Therefore, "the sound must be broken"-that is, intermittent. This problem should have nothing to do with the audio bus and sound card driver.

You "try to uninstall HD audio", which is simply a "dangerous" action-because this is an audio-driven bus program, what does this mean? That is, whether you have a sound card or not, it should exist, which is the control; And if you install a sound card, then you have to install the driver of the sound card, or play-for example, if you install a Ruiyu brand sound card, you have to install Realtek high-definition audio-the two high-definition audio are just the same name, not the same program or the same function.

(3) Therefore, to solve the problem of "broken sound", we should check the tightness of the connecting wire and plug of the audio equipment, and see if there is dirt or oxidation that leads to poor contact-clean it (you can plug it in with a drop of sewing machine oil of 5 yuan, the most common bottle in the shop), ok? In addition, you can also use headphones to plug into the headphone jack (light yellow) of the computer case for monitoring test to confirm that it is a problem of poor audio connection. I wish you success and happiness ~ ~
