So my sound stopped working.
I'm using the component cable that I got with the 360 when I bought it back in '06.
It's hooked up to a full hd samsung lcd, a pretty good one (cant remember its factory name).
My ps3 is working with sound, as does the sound when I watch regular television.
I've checked the mute button!
The 360 used to work like normal. I haven't touch it because of school and work (around 3 months).
Hrm.. what else.. well cant think of anything else but I hope that someone knows what might be wrong with it.
