baku, what are you plugging your DSS to? If the DSS is getting a Dolby Digital signal, there is no way it isn't doing proper Dolby headphone (the light should be on).
If you're gaming on PC... your PC has to have an optical out that is capable of sending a olby Digital signal. For example, my Alienware laptop has an optical out, but it ONLY does 2 channel pcm, no Dolby. In order for me to get Dolby from my PC, I have to use my Xonar U3 external soundcard. It does Dolby Headphone OR it can send out an untouched Dolby Digital signal if you really wanna use the DSS.
Rereplying because mine got lost in the last few posts.
I'm using this:
I have an optical cord going from that to the DSS annd from the DSS a 3.5mm to the headset.
is that external sound card my weak link?
Do I need to buy a new usb sound card? What is the DSS considered? Is it an amp? Do I need it?
