Win7 system computer noise solution

Next, here's how to solve the noise problem of the win7 system. However, the situation I encountered in Xiaobian is the problem that appeared in the High Definition Audio series, so I can only talk about my solution for this aspect. As follows:

If there is a problem, of course, the first step is to need to re-install the relevant driver completely, which can eliminate the noise problem caused by the driver. After the installation is complete, we can go to the control panel of the system. In the system's panel, you can find the REALTEK HD Audio Manager option.

In the first step, we found the "REALTEK HD Audio Manager", which we double-clicked to open.

In the relevant panel that opens, we go to the "Speakers" tab. In its tab, you will find the "Default Format" tab in the lower position. In the format, switch to "16 bit, 44100hz (cd quality)". After the change is completed, you can try it a bit. Do you feel that the noise is much lower? In the default format, there are many options, but the more the options are, the corresponding sound card requirements are more serious. If the sound card does not meet the requirements, the noise will become more and more serious. Therefore, this item should be specifically selected according to the condition of the sound card.

Choosing an item does not completely eliminate the noise, but also other operations. Enter the registry editor, expand the "hkey-local-machine/system/currentcontrolset/services/audiosrv" option, find the "dependonservice" option in the right side and double-click to open, delete “mmcss” save and exit, then Restart the computer.

Finally, find "Services" in "Computer Management", and finally find "multimediaclassscheduler", we will set "Startup Type" to "Disable". In this case, the operation settings are complete. Generally speaking, if it is due to the above situation, then such a method can solve the problem of system noise perfectly.
