I'm sorry if I missed something obvious but I've tried asio4all and wasapi with foobar 2000 with the appropriate plugins and I still fail the dts test getting nothing but a hiss from my speakers with dts sample files. When using wasapi music sounds fine and works great but it's bugging me that it's not bit perfect. What's confusing is that with wasapi the windows volume slider does nothing which makes me think it's working. The foobar2000 volume slider does work however. I got the dts test tracks here http://www.diatonis.com/surround_sound_music.html and I'm running an optical cable from my asus p8z77-v pro motherboard to a harmon kardon hk3490 receiver that can supposedly decode dts. The motherboard has realtek alc892 onboard. I haven't been able to confirm whether or not it should actually be able to do bit perfect but it seems to have a fairly modern feature set.
Realtek® ALC892 8-Channel High Definition Audio CODEC
Any ideas? I'm sure I'm just missing something simple. Thanks gents.
