So I just received the monoprice male mini-display + male usb audio to female hdmi... when I connected it to my tv it worked great. I changed output for audio to usb and safari and vlc worked great(i.e. hd youtube clips play without hiccup, 1080p movies work, 720p tv shows work) The only problem I had is when I open plex my sound suddenly goes from coming out of the TV to coming out of the built MBP speakers. What confused me is that sound effects ( when I raise or lower the volume using the shortcuts ) come out of of the tv speakers but the movie sounds come out of the MBP. I tried to look at settings in plex but I couldn't figure it out. Anyone know how to fix this?? Help is greatly appreciated. I only mind because there are a couple of movies that don't work on vlc but work on plex.
