I just put together a HTPC from spare parts lying around work (some random Foxconn mobo, Intel Core 2 Duo, 4 GB Ram, 1TB Hard Drive) and slapped Mint 15 on it. For the video card, I am running a Radeon HD 5450 through an Onkyo TR-NX1515 to a VIZIO e551i-a2. My primary concern is the lack of audio. There isn't even an option to select anything but Analog out in the settings. I have done some research on this and everyone else seemed to at least have an option for the HDMI audio out. My secondary concern is that the view isn't filling up the entire screen. The outer 2 1/2 to 3 inches is nothing but black. I have tried different aspect ratios, resolutions, and zoom, but all still have the blank field around the edge. Does anyone else have any experience with these issues?
