I just tried using my Monoprice mini displayport to HDMI adapter with my 2010 MBP connected to my TV. Audio did not work. So I'm wondering if I'm missing a setup step on my MBP or if maybe the monoprice adapter is out of date (according to Apple only adapters with VESA 1.1 or higher are compatible w/ the 2010 MBPs audio out feature and I bought the adapter a year ago). I did go to the audio pref pane but did not see any output option for MDP -- only internal, and soundflower (used by Audio Hijack). Has anyone had any luck with the monoprice adapter and if so when did you buy it? (Wondering if maybe the current model has 1.1).
