Channel order wrong on Mac 2.1.0

there's a regression in channel order with the Mac 2.1.0 nightlies. I first noticed it on a video with a TrueHD 6 channel encoding, but it also happens with these test files: http://www.lynnepublishing.com/surround/www_lynnemusic_com_surround_test.wma http://www.lynnepublishing.com/surround/www_lynnemusic_com_surround_test.ac3

left, right, and effects channels play on proper speakers. Center and rear left swapped, rear right also plays on center speaker

2.0.7 nightlies working as intended.
