Thanks for the advice and the burp
It is an optical, and it is a cheap one. I plugged up my Microsoft optical, and I'm back in the groove now. The trash can has a new friend. I'm still learning about the little problems, so sorry if this was a stupid question. [A first-build takes some work, but I feel confident that I'll be able to build future rigs with little difficulty]
edit: Oh yeah, I know the X1600 is pretty crappy in relation to the 'big boys,' but I got it for 100 bucks from Best Buy, the day after Thanksgiving ("black Friday." After the fact, I realize that I could have just put another 50-75 to get something better, but I don't think it was too bad of a move for a rookie. Is this a reasonable thought?
