this came with the intergrated sound devise on my sister's computer, and her speakers don't work. She called tech support and they told her she needs new speakers, souround sound 5.1. she felt the need to ask me and I told her I have no idea, I've had my speakers longer than she's had hers and I've never had to upgrade. I just get new sound cards like blaster to audigy. there's only three ports in the back: audio out, audio in, and microphone. does she need these new speakers?
