about a month last 3 weeks i bough a Xbox arcade from game tower cheras...

now i have a serious problem regarding the sound quality.

i prefer to use the HDMI to connect to my Samsung T240 LCD with FullHD output.
but my Hifi receiver is running on Optical cable only.

So i have to output the HDMI cable from Xbox to LCD, then only can output Optical cable from LCD
to Receiver...

i still remember last time when i play PS3 the sound is loud and nice with hard Bass...

now with Xbox setup, i have to turn on to -25db only can feel it is loud.
compare to PS3 direct output from Optical cable is -45db.

any expert please help me to solve this problem....thank you very very much.
