If you were to go back to your home screen after looking at the live screen the audio would stop. Unfortuantely, we do not have a feature that would keep the audio going.

Another issue stemming from that is that the live view will show for 10 minutes, then prompt  you if you want to keep viewing the video.

Is there any way to override the 10-minute prompt? I too am trying to use it as an "always on" baby monitor for the few hours between baby going to bed and when I myself go to bed.

@Sheepworrier agreed, I found this out the hard way.
