# testing behavior with inactive channels (i.e. no data receive):
# - 4 audio channels are used in SDP
# - UAC has channels 0,2 and 3 active, UAS channels 0,1 and 3
# - both use RTP send_recv
# - expected is that UAC sends from 0,1,3 (i.e. active on UAS for receiving
# traffic) but receives on 0,2,3. UAS sends on 0,2,3 and receives on 0,1,3
