Hi Samuel,
Thanks for your advice I have implemented yours suggestion but found
the streamed output is ramping up and down by that I mean the volume
increases and decreases where it did not before. I have added an entry
to the input.alsa
stream = mksafe(normalize(audio_to_stereo(input.alsa())))
but don't think that this has anything to do with the op was fine with
output.dummy
