I strongly suggest you try using a packet sniffer before you stubbornly engage in arguments about what they can and can't see. I will send you $100 if you can configure wireshark to do what you describe. Using any of the tools in this thread, or any of your own, go ahead and try capturing even 1 packet from an audio interface in wireshark and post the pcap file. It's not over anyone's head - we have interns who understand why this doesn't work. I have no idea why you might think it would.
