When at the monitor if I select channel 1 on the single channel screen the audio works fine, on the 16 channel screen I am unable to select the audio so nothing is heard. Accessing from the web app and using the 16ch screen I am able to activate channel one audio but not from the monitor. At the monitor the speaker symbol is grey and will not change when the mouse is on the speaker symbol. Am I missing something this should have the ability to audio out for the selected channel on a multi channel screen?

Thanks
