Noise solution for Win7 system computer

Next, here is a description of how to solve the win7 system noise problem. However, I met the situation is in the High Definition audio series of problems, so I can only address this aspect of my solution. As follows:

If there is a problem, the first step, of course, is to reinstall the driver associated with the installation, which eliminates the noise problem caused by the driver. Once the installation is complete, we can enter the control panel of the system. In the system panel, you can find the Realtek HD Audio manager option.

In the first step, we found the "Realtek HD Audio Manager", we double-click to open.

In the related panel that opens, we go to the Speakers tab, and in its tab, you'll find the default Format tab in a slightly lower position, and in the default format, switch to 16-bit, 44100hz (CD-quality). After the change is complete, you can try it a little bit, do you feel the noise is a lot lower? In the default format, there are many options, but more to the back of the options, the corresponding sound card requirements are more serious, if the sound card does not reach the requirements, the noise will become more and more serious. So this item should be based on the sound of the situation to the specific choice.

Select one, it does not completely eliminate the noise, but also to other operations. Go to Registry Editor, expand the "Hkey-local-machine/system/currentcontrolset/services/audiosrv" item in turn, locate the "DependOnService" item on the right and double-click to open, delete "Mmcss" Saves the exit and then restarts the computer.

Finally, find "service" in "Computer Management", finally find "Multimediaclassscheduler", we set "Startup type" to "disabled". In this case, the operation setup is complete. In general, if it is due to the above improvement, then this method can be perfect solution to the problem of system noise.
