Question regard the Samsung 32 inch LCD TV (550 series)

I just recently bought a Samsung 32 inch LCD TV (LN32D550K1F). It has the SRS audio feature which I can use for regular TV programming. However, it won’t work for cable programming or gaming. Why? Is there a way for it to work with cable programming and gaming or not? Thank you!
Answer #1
I think it’s part of the TV tuner so using inputs like HDMI or component bypass it
Answer #2
Having read the manual,I can’t really see why it should not work at least on cable TV, unless it is only for digital TV or something like that..
Suggest you contact Samsung with that query..
( I was referring to cable TV that is tuned in by the Samsung, btw).
