Onboard. SoundStorm™ Technology - It was/is comparable to Audigy sound quality. Audigy 2 I don't know about, probably not as top notch, but good enough for me.
I like my 4.1 speakers, so I went and got an elcheapo $15 no name card. Works fine and my Creative 4.1's (I bought them for $60 at WalMart two years ago) make my ears bleed. Ya can hear em two floors away, clearly.
I have the Live! card and I love it. I want to invest in a new card as soon as possible, but right now for $20 it does the trick. Optical would have been nice...
onboard.. nothing else to it.. i dont need an entertainment bass boosting speakers thumpin' computer speaker.. i have a car and boombox for that sorta stuff..
there are other cards than sb you know lol. I got my 5.1 card for free, i think its called predator made by maddog entertainment. its pretty good considering it was free =D
It's not too bad. If it ever gives me problems, I'll just yank it out and upgrade. Not sure what I'll go to though. I don't like Creative's software and crap...
