Hello,
We use pulseaudio in our LAN and we've noticed that the default Multicast
IP Address (ie 224.0.0.56) used by the module-rtp-send and module-rtp-recv
seems to be part of the "well-known" Multicast adresses. As a result, some
switches (HP Procurve in our case) won't filter the igmp traffic, but will
broadcast it to all ports. I attached a documentation from HP Procurve
Networking with better explanations about this on page 100, (4-22).
We had to change the multicast IP address to resolv that issue. It seems
that the 239.255.x.x range is dedicated to local multicast diffusion. We
use 239.255.1.56 and it now works perfectly. My request is to have the
default multicast IP address changed so that multicast diffusion works in
all case with all network materials.
I would be glad to provide more information,[[br]]
Best regards[[br]]
