So for my birthday i was bought some astro a40's (with the mixamp pro) and my mobo doesn't have the right input to be able to use the 7.1 surround. I need a sound card with a toslink output which will go to the mixamp. Is this sound card suitable?? http://www.newegg.com/global/uk/Product/Product.aspx?Item=N82E16829102063
