Just got it working, easy as raspberry pi. Goes through my amp with the TV off now I have the spdif splitter.
I assumed it would have some GUI on the TV too so I thought it wasn't working at first. Nice web interface on the phone, but lines of text too long wrap over themselves and makes itnimpossivle to read some things.
Working well so far. I've found the Sound@home app a bit easier to use due to the overlapping text in the web app. It doesn't have the library so have to browse the folders instead, not a problem.
My old Creative speakers are a bit shit though. Need something in between them and my far too big for the room speakers.
Have to remember to keep the playlist topped up later when people get here. Good find Ant :)
You're welcome.
Hope it worked out well.
