In order for amp B to receive audio from source 2 on amp A, amp B must know the eAudioCast device ID for A, a UUID, and the 0-based source position on that amp. This source position does not correspond to the source IDs used in the source selection command (03). Rather, source 1 is 0, source 2 is 1, etc.
