i have a problem in sound with my Onkyo Integra ds989 receiver... It is connected via optical cabel to my PC, in video player i sellected SPDIF for sund output, so digital signal is passed directly to receiver, that way surround is great, but there is no strong punch, bass is weak, speech in the movies is also to quiet.... On the other hand if i let my onboard soundcard process the sound, it becomes strong, like i want, but surround is bad... so, oposite situation from SPDIF ... In receiver i can boost central speaker and bass levels, but i dont achieve much .... So is there maybe some hidden option or something ? Or should i buy good soundcard, i was thinking about asus xonar? and connect it with coaxial cabel to PC... Please help!
