Description

When playing 5.1 surround FLAC files over HDMI, the rear-left and LFE (subwoofer) channels are swapped. Only the low-range portion of the track comes out of the rear-left speaker. These same FLAC files play properly on a PC and other devices through every software player I've tried.

It seems this same behavior is exhibited when playing back 5.1 .wav files even when they've never been converted to FLAC. Details in comments here: BOXEE-11142

Why is this classified as minor?

For 6.1 FLAC it's even worse, front center is output in front right speaker. Makes it impossible to watch movies, who wants the dialogue there?

See FLAC spec for "channel assignment" here:
http://flac.sourceforge.net/format.html

The correct channel order is:
1 channel: mono
2 channels: left, right
3 channels: left, right, center
4 channels: front left, front right, back left, back right
5 channels: front left, front right, front center, back/surround left, back/surround right
6 channels: front left, front right, front center, LFE, back/surround left, back/surround right
7 channels: front left, front right, front center, LFE, back center, side left, side right
8 channels: front left, front right, front center, LFE, back left, back right, side left, side right
