Thanks very much for your quick reply, I did find the answer to which port is audio out.
Just curious if you (or anyone) might have an idea why all I get is noise on that port? I’m using a standard 1/8" to 1/8" audio cable connected to computer speakers. I’m guessing I may need to play with the audio out settings in XBMC, and normally I would just experiment with that but I’m also struggling with HDMI compatibility with the crappy little TV in this rental place I just moved to! So if anyone knows and has a minute to answer that’d be great.
I changed the audio device settings to the default (which still appears as an HDMI port) and set the speakers to 2.0 and now sound via the audio jack works fine. I’m normally hooked up to a 5.1 audio system and I’m not sure which change did the trick but good is good.
