Hi Leonid,
I have initially run the test exactly as you described: two instances on the same machine, and, in order to avoid errors in typing the IP and ports, I have copy & pasted the info from one instance on the other.
After that test just to confirm the streaming (the play side of the test) was ok I started the streaming again sending it towards another host (my workstation) where I have captured the stream with wireshark: output stream is ok, I've made the playout of the captured RTP stream and audio was present and clear.
My understanding is that there's a problem in the receiving path (even because in our application I can also confirm we ear the audio so dx/play --> ipm/streaming RTP is definitely ok), is there any way to perform low level debug on the system or do you have any other suggestion?
Thanks,
Alberto
