Been covered before. It's a known bug, I am also eagerly awaiting a fix.
1.0.8 don't have this issue, might be worthwhile downgrading (that's what I did), but at the same time I also miss the bug fixes and changes in 1.0.9 and 2.0.0.
I also found if you set your playback to raw 5.1, it will at least pay 2.0 for aac 7.1 content.
