Comment (by cehoyos):

 Replying to [comment:2 rogerdpack]:
 > so, just for reference, if you don't use -aac_coder 0 you get bad output
 too, is that right?
 As said, I found the same problem - that is a regression - approximately a
 year ago (also testing an artificial sample), as a result -aac_coder 0 was
 added, and since it is not default, I suspect that the problem is not
 reproducible with a real-world sample (but I never tested)-
 If that is wrong (ie if you have a real-world sample that is encoded badly
 with the default coder regarding the surround channels), please share the
 sample (and test with -aac_coder 0 and / or provide a patch to make it
 default).
