Re: [Jack-Devel] connecting jack between a linux audio master and a windows slave

so I have run more tests.
I unload "netmanager" in the linux jack master , but keep tcpdump running
for packets on port 19000 on that pc.
Then I run jack as master on the windows pc and also run a general purpose
multicast packet sniffer on windows , set to listen for packets in the jack
default address and port. Both tcpdump and the windows multicast packet
sniffer do receive the packets.
Additionally, using "netsh" I verified that multicast address is registered
for 2 applications (reference=2) as expected. However, once again packets
seem to be leaving from the linux jack client, they are intercepted by both
linux and windows jack_master pc's , but the windows jack_master does not
respond.

What could be wrong? is it possible the jack application does not receive
the packets for some reason? Do I have a way to check that?  is it possible
that somewhere internally jack chooses not to send replies???

thank you in advance for your help.
