I have a Hikvision DS-7716NI-SP/16-1TB. I also have one camera that has one way audio/microphone. Problem is that if I put it on my monitor single screen I can hear the audio (which is what I want) however, when I choose multi-screen view (16 cameras) I cannot hear the audio/microphone. Its muted. Is there anyway to have the 16 channels displayed with the audio playing? Thanks in advance
