I'm looking to buy a sound card to connect my PC to my philips HTiB. The problem is that my HTiB does not have an optical input, only coax. So I will need a soundcard which supports coax. Also, is there any sound card, which accepts opt in and converts to coax out so that I can connect my PS3 to this as well (apologies in advance if this sounds stupid) 
Budget: I'm not really aware of the sound card market, I would say cheaper the better
