Hey guys... I have a Mid-2011 Mac Mini with two monitors, one is connected straight HDMI, the other is connected via an HDMI->Thunderbolt Display adapter. I'd like to get sound working on both monitors at the same time (individually, I can alternate HDMI output between them). I tried going to Audio Midi Setup and creating an aggregate device or multi-output device and neither worked. I suspect the issue might be I am trying to use multiple HDMI connections at the same time? Do I need to try using VGA -> Thunderbolt adapter instead?
