But I can't find certain solutions from googling.

You don't specify which operating system you are using, but you need to download the Windows Driver Kit (WDK)[^] (The link is for Windows 10)

By installing the WDK the command line tool DevCon[^] will also be installed.

Quote:
DevCon (Devcon.exe), the Device Console, is a command-line tool that displays detailed information about devices on computers running Windows. You can use DevCon to enable, disable, install, configure, and remove devices.

The source code[^] for DevCon is available as well, so you can see how things are done in this application.

I hope this info will get you started.

I have tried with devcon.
When I have executed "devcon hwids *", I could not find stereo mix device on the list.
How can I find solution.
I think I can enable or disable all the devices on my computer using devcon, but there is not the device that I am looking for on list.
What can I do in this time?
I wish helps.

Is a stereo mix device a hardware device?
Can you find the microphone?

Stereo mix device can not be said as hardware device. But it is supported by sound drivers to "hear my voice" from my computer's outputtings.
I am using microphone, but I can't find 'microphone'.

I will show my test works.
1. devcon hwids * > files.txt
2. open files.txt
3. Ctrl+F > microphone
4. it says that there is not such word.
That's all.
I am beginner in hardware programming.
I appreciate your helps.
I think you can help me sure.
Thank you very much.
