I have a creative x-fi soundcard for gaming, unfortunately the digital(SPDIF) out can only carry 2 channel signal, from what I understand all creative soundcards can not carry 5.1 or 7.1 signal over the optical or coax cable for gaming, watching DVD in 5.1 or 7.1 is fine though. So, is there any other soundcards out there that would allow me to use the digital output with multichannels for gaming? Im using the Marantz 7.1 A/V receiver.
