at the minute my 2009 mini is connected by VGA to my bedroom cheap tv (almost all of my tv viewing is internet based due to living in portugal and watching uk tv and netflix) i dont get any sound out through the cabling so have to use separate speakers but its a pretty low fi setup so its not an issue. however the mini might get a promotion. the android tv box connected to the 4k tv in the lounge is unstable, constantly crashing. i could buy a new faster better one, but if i can solve the sound issue then id like to use the mini as a internet tv server and plex server (guess i could do that anyway) what are my options? i take it hdmi doesn't carry sound either? i saw something about optical sound, but i dont think the 2009 mini would have that? is using the audio sockets really affecting the sound quality?
