(Basically, I'd like to play some sound over Skype while still > being able to have conversation.) 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) -Pierre
