I'm trying to let someone hear all sounds played on my Mac while talking in Skype. Simple test: call Skype test while playing Youtube music and talking, both talk and music should be recorded and played back.
For this I created two devices in Audio MIDI Setup app:
- Aggregate device (Built-in Mic, Soundflower(64ch)) and
- Multi-Output device (Built-in Output, Soundflower(64ch))
I selected them as default input and default output correspondingly.
Depending on ordering of Soundflower and Mic in Aggregate device either only talk or only music is recorded.
How to change Aggregate device to record (transfer in Skype) both background music and talk?
