Thanks you very much!

Ok. I've been trying to reproduce here without luck so far. However,
before we go on, have you tried the script without the buffer()
operator?
This operator does much more than add a buffer, in this case, it will
create two clocks, one for the ALSA input and one for all the icecast
output (I think). In your case, this does not make sense I think.. :-)

Yes, this one is to be expected. The mono output expects a mono source
but your radio source is stereo. You need to use the mean operator
here:
output.icecast(
%vorbis(samplerate=44100, channels=1, quality=-0.1),
host = "hostname", port = 7900,
password = "hackme",
mount = "radio.ogg",
mean(radio))
