> 
> Using that setup and a pair of stereo speakers or headphones, I ran
> "speaker-test -D surround51 -c 6 -t wav".  The audio for the front
> left, front center, front right, rear left, and rear right speakers
> came through just fine (and even sounded spatially correct with

Could you please update to the latest version and test again?
