DISCLAIMER: This might be a really stupid question... it possibly may even be the wrong forum! ..but does anyone know how on earth I can upmix my line-in signal? I want to plug our TV into the PC soundcard in the games room. Sadly AC3Filter, CMSS and a few others only upmix system sounds. All Line-In source is stereo. I'm using a Audigy2 (with SPDIF model) via Line-in My Wii (RCA), PC (VGA and HDMI) and cable box (SCART) connect to the LCD. I'm simply connecting the TV's headphone to the Audigy's Line-In. Sounds great -but only in Stereo. I have an upmix button on our G500 Pro Gamer speaker remote -but it just sounds too spatial for TV. If anyone can help us get better ProLogic through Line-In it would be great. I've been searching all day and quite frankly - I must suck at Google.
