Transcoding only multichannel dsf files

[Veganfloyd]

Thank you, Simon. I believe that the pan option/function is the best one for this purpose, so here is my 'best try' for it:

convOut=-af volume=+6dB, -af pan="5.0| c0=c0 | c1=c1 | c2=c2 | c3=c4 | c4=c5"

I tested different flavours with added/removed commas, quotes and the volume option, but to no avail.
