Is there a possibility to change microphone sound level using Windows Registry editing tools, eg. Regedit or REG command?

Question

I'm making a script to change parameters of a microphone (name, sample rate, bit depth, channels and sound level) but I cannot find any subkey for sound level.

I checked if I can modify that value using Regedit by changing this value in settings, exporting Registry files and then comparing those Registry files, but it haven't shown me anything.

I also searched for "HKEY_CURRENT_USER\Software\Microsoft\Multimedia\Sound Mapper" subkey in Regedit, but I haven't found it.
