FL+FR+BL+BR
What is the correct answer?
Both.
Left, assumed to be front (L) = Front Left (FL)
Left surround/side (Ls) = Back Left (BL)
etc
(that's part way down the AudioChannelManipulation page, even farther
down is a list of the channel names and standard layouts, also in the
-layouts output)
z!

Are you sure for good Carl?
AFAIK, LS is surround and BL is back/Rear
Please look here
https://mediaarea.net/AudioChannelLayout
They say, depending of standardization;
Left Surround = Ls = CL = SL = Ls (MediaInfo name)
Right Surround = Rs = CR = SR = Rs (MediaInfo name)
Left Rear Surround = Lrs = BL = Lsr = SL = Lb (MediaInfo name)
Right Rear Surround = Rrs = BR = Rsr = Rb (MediaInfo name)
