i didn't find anything about tagging flac files as surround files. i think there should some possibility to tell the player how to play a multi-channel file (how to map the different channels to the speakers
or if there some decode is needed, like for ambisonic files).
it wouldn't be in the tags, it would be a specific channel assignment in the frame header:
http://flac.sourceforge.net/format.html#frame_header
there are currently none defined for >2 channels but there could be.
i would write a proposal for this, but i don't think 4 bit is enough for all the different surround formats. for example in a ac3 encoder i can define any combination of left-right, center, surround and LFE channels.

there are different channel profiles for 5.1: L R C LFE Ls Rs (DVD) L R Ls Rs C LFE L C R Ls Rs LFE (Film)
then we have ambisonics where we have 1st, 2nd and 3rd order (4, 9 and 16 channels), but then you can also have 2 dimensional ambisonics without heigt signal, which gives another 3 options, plus different UHJ encoded variants, etc.
how can we squeeze this in 4 bits?
