I know this isn’t wholly a motherboard question but don’t know where else to post: my motherboard the Asus Apex IX came with only stereo sound since it’s an extreme overclocking board and they figure people don’t care. I’d like to add surround but my graphics card is a three slot so it would have to be externally and my surround headphones are USB powered . Do they make an external sound card that will give my pc surround capabilities or I guess the driver , so I can plug into other USB ports and not directly into the surround card adapter. Or worst-case scenario does anybody know of a relatively cheaper surround card that has a USB port I can’t seem to find one?
