Yes, they're moving as they're should. I'm sure it's playing in 5.1, however the driver/codec is downmixing it to stereo when in DTS/DDL mode. (Or perhaps is actually just outputing stereo PCM, I have no way to tell from my receiver.) SoundCheck reports Realtek Digital Output as 2 channels when in DDL/DTS mode. Can anyone who got it working check how many channels it is supposed to report?
