Comment (by calestyo):

 Sigh,...
 Carl, this ticket is obviously not spam or invalid... you've already wrote
 me in private that you're likely not going to technically work on it... I
 did write in my text that the console output are contained (and even if
 not, one would have easily seen it from looking at the tarball).

 So not only do I think it's perhaps not the best approach to blindly close
 such a ticket without barely looking at it... but why do you insist on
 special forms of posting?
 You may prefer having the output directly in the ticket, the next one may
 think it clutters that up,... the next one would like to have it one
 pastbin, another one on facebook and so on.

 Apart from that, I'd rather doubt the console output tells much of
 worth,... there is not error in terms of an error message happening...
 it's just that the audio produced is not as it should be.


 Anyway... copy&pasting from ffmpeg-git-decoded.tar.xz’s log.err:
