I'm not sure which forum this belongs in, so here goes... I have a Denon AVR483 hooked to my computer via the 6 channel discrete inputs. If I am playing stereo music or playing a game, my subwoofer does not output anything. Granted there is no LFE channel, but shouldn't it reproduce frequencies below a certain point? All my speakers are set to "small." When I hook my computer to my receiver via 2 channel analog or toslink, my sub works properly. Is this a limitation of the receiver or is there an option to have the sub reproduce low frequencies from other channels?
