ok the problem here is that the second step:

inputs = mux_stereo(inputs,inputC) # inputs redefined to a 6-channel sources

your inputs is already a quad file so mux_stereo will fail

i tried this with mux_mono

# Set global setting.
set("frame.channels",4)
inputa = sine()
inputb = sine()
inputc = sine()
inputd = sine()

inputs = mux_mono(mono=inputa,inputb)
inputs = mux_mono(inputs,inputc)
inputs = mux_mono(inputs,inputd)

output.icecast(%vorbis,host="localhost",port=8800,
mount="quadvorbis.ogg", password="xxxxx", fallible=true, inputs)

would it be possible to have something like:

inputs = mux_mono(inputa,inputb,inputc,inputd)
with the resultant inputs having 4 channels

thanks
