Teka teka ganito:
yung PowerDVD or other software - dd and dts 5.1 capable
of course this needs to be send to the speaker via thru sound card's output
yung sound card may front L/R, rear L/R, center/sub, etc. kaso wala nakalagay na DD or DTS pero 5.1 channel sya...
then i have the correct speakers for the sound card's jack...
dolby or dts surround/5.1 ba output nun?
