Is there a setting in BI5 that prevent audio during live viewing? I noticed in UI3 during live viewing of video the audio can be heard but not with the BI5 GUI. I've got the green audio enable turned all the way up on both UI3 and BI5. When I play back stored video/audio in the BI5 GUI I can hear sound just fine. And yes, I am playing at regular 1x speed.
If you are using RDP to remote in to view BI GUI and are running as a service, then you will not get live audio. Not running as a service and you will get live audio.
