Hi I'm new here and still figuring out the cameras.  Is there a way to mute live playback but the camera still records audio? Sometimes I like to peek in on my cameras while away and I'm in a quiet area. Because of this I mute sound (I know I can turn down my phone) , but sometimes I can't do that fast enough. 
I notice when I mute.. my camera doesn't record audio either. Is there a way around this? Is there a way to mute live sound playback without turning off the microphone?
I have a SD card for playback. 
I have C211 and C110
