Windows 7 32-bit system

Before executing a certain audio, you need to first determine whether the system is muted:
1. If it is in a muted state, unmute it, then execute the audio file, and then re-mute it after execution.
2. If not, directly execute the audio, and after it ends, re-mute it.

Can batch processing be achieved?

I sent the link to that group and let them take a look.

"Obtaining and Setting the Volume of Audio Devices under the Windows System"

A bit professional, really don't know where to start, I just know how to change file extensions. Can you please post the code here, and I'll change the audio file path myself (I can't compile. And don't understand C++)
