Leif,
This solution also works for StationPlaylist Studio! Setup Breakaway Live as previously instructed.
In Studio:
Add the LiveLink dll to the engine/plugins folder.
In the Output settings select "Null output".
In the Digital Signal Processors Section Check the "Breakaway-Live Livelink1".
And also check Oddcast DSP so you can stream. (Make sure Oddcast is below Livelink in the list). No need to set up an encoder within Breakaway.
Voila! Streaming processed audio from a computer with no sound devices!
Edit: Just noticed you replied with the same answer. I’m so observant!
