I have the above panel interface on my computer, and have a sound blaster SC, with Creative 5. speaker system. I just started using my Samsung as a tv, and not just a monitor. When Im on the PC sound is great and speakers/sub work, but when I use tv i get micro speaker sound and quality from tv. Tech support from Samsung said I need to use optical cable. Well I hooked up the optical out to the optical in, and still no speakers from the 5. system.
