Description
Mplayer plays multichannel flac files as if they had channel order like: FL,FR,RL,RR,CEN,LFE.
The flac spec says that 5.1 flac should be encoded FL,FR,CEN,LFE,RL,RR.
This channel mismapping results in messed up surround sound for standards-compliant multichannel flacs. Here is a flac with "correct" channel mapping that can be used to confirm: http://137.222.225.69:8008/Multichannel_test_flac_standard_6.flac

These files play with the same order for me, and at least with -ao alsa that is the correct order:

Please make sure to test with latest SVN (though this should be fixed since many, many months already) and provide more details if the issue persists for you.

Sorry, it's my mistake. Problem not in channel order. ffflac not downmix channels and one can hear only first two on my 2.0 audio system.
Years pass but bug still alive. Now many video files contain audio tracks in multichannel flacs. This bug makes big trouble of watching that video. Sorry for my english.
