SB Platinum EX Q

Yeah, I know this isn't a LIVE card.. *hanging head*

I just upgraded to this card.. worked perfectly.. Alas, my system had
been overheating and the tech had to order a new case when he
installed this card for me. The card/etc was perfect.. loved it!

I went back in so he could switch cases.. Now the nightmare begins.
I won't go through the whole story.. but.. now I have perfect sound if
the headphones are plugged into the card itself. But, if I plug them
into the external console.. only left speaker.

Any ideas what is happening here?

I've searched the Creative site with nothing even remotely matching
this.

Thanks!
*sigh* lol
