Hi, I'm writing in desperate. I got those 5.1 speakers and those sound great, can't wait to take them home on my pc. But it'll be awhile before then. I notice that my laptop even with those speakers only sound loud and not crisps. So I want to find a usb sound card, so I don't have to switch back and forth with my 4port usb on laptop. I was thinking I could use that usb on my pc at home as well, please help! Thanks.
