The 

 read command returns the microphone mute and supply voltage status.

The 

 write command can be used to switch the microphone's audio path (muted / not muted) or to con-

trol the power supply of the VMIC line for the two microphone inputs. 

The microphone can be muted or activated by changing 

 in all audio modes (1 to 6) and during a

voice call only. As an alternative, you can use the
