I worked on something similar for the loopback module, it included a new
'uplink-sink' to mix music/tones with a source. It did not however take the
samples from an actual output, you'd have to use module-combine to play on
both sinks.
If you are interested I can try to find it in my archives (I thought I had
submitted it)
