Long story short, I got a new 2010 Mac Mini recently. I initially connected it to my HDTV via HDMI and OSX detected that it was a Samsung television. Now, whenever I go into System Preferences > Sound > Output, Samsung shows up when I selected HDMI. I've since connected the Mini via HDMI to my audio receiver...but it is still coming up as Samsung. I've been having problems getting 5.1 surround sound working (only the front speakers work) and I wondering if this is because it still thinks it is hooked up to a tv and the tv cannot output in 5.1... just in stereo. I've tried rebooting multiple times and I even called Apple but the guy I spoke with was of no help whatsoever. He had me hold the power button in and everything...nothing he suggested worked. Basically what I'd like to do is remove Samsung from the list and force it to see my receiver just like when I first turned on the system. Anyone know the correct way on how to do this?
