Hi all,
You should be able to achieve this using mux_mono:
http://liquidsoap.fm/doc-svn/reference.html#mux_mono or
liquidsoap -h mux_mono
Mux a mono audio stream into another stream.
Type: (?id:string,mono:source(audio=1,video=0,midi=0),
source(audio='#a,video='#b,midi='#c))->
source(audio='#a+1,video='#b,midi='#c)
Category: Source / Conversions
Parameters:
* id : string (default: "")
Force the value of the source ID.
* mono : source(audio=1,video=0,midi=0) (default: None)
* (unlabeled) : source(audio='#a,video='#b,midi='#c) (default: None)
