i have a nexus s sat pci in my dell 2400, it has a plug with cables that attach to the line in on the soundblaster and rca jacks yellow and white that attach to the tv. the sat program controls the sound to my desktop speakers, there is no problem there, with the speakers off and soundbar maxed out the volume on the tv is low, the soundbar on the tv has no control on the volume. dont understand that!!!! do i have to connect the white rca jack to my soundcard somewhere and then run another cable from the soundcard to the tv audio jack? can you help, rgds, veldog
