Comment:
The new behaviour is reproducible since release 0.9, apart from what
Hendrik wrote above I believe there are two additional good reasons why it
should not be changed again:
{{{$ ffmpeg -i mono.wav -channel_layout 7.0 out.wav}}} would produce
surprising output if we copy sox's behaviour (upmixing to more than two
channels did not work before 0.9)
The behaviour you want can easily be achieved using the pan filter.
