OMG i found my solution here thanks for the smart insight on this thread
i have succeed on setting APO on my 5.1 soundcard and the EQ and filter works my speaker setup for now is Stereo & Subwoofer. but now i want to add Usb Dac to my Setup for now my connection is Usb Input to Dac > Output Dac to Line In Soundcard > Filter & EQ Apo > Output Soundcard to amplifier but when i select my playback via Usb Dac there is no sound when i select my playback to Soundcard it works but the Dac is bypassed what is the correct routing to use 5.1 soundcard and Usb Dac dongle ?
