After searching a lot about 7.1/5.1 External USB Sound cards that are OS X compatible, I still haven't been able to find one that is (still) sold today. Yesterday I bought this one: Trust 5.1 External Surround Sound Card, but had to return it after testing. This one turns out to be Windows only. A next option would be this one: Sweex 7.1 External USB Sound Card, but I don't want to end up returning it as well. Could anyone help me out here, please? All I want is something to be able to use all 5 speakers of my Logitech X-530 set, instead of just 2. I just want to hear sound come out of all of them, so I don't want an expensive sound card. Would the Sweex 7.1 External USB Sound Card do fine?
