Hi, to connect a host with ?arecord -Dpulse -r48000 -fS16_LE -c2 | pacat -p -s 141.56.112.122 --rate=48000 --channels=2 ?format=s16le? works. It was the exact idea that pacat and arecord have different defaults. And so the data is not compatible. But this isn`t a satisfied solution for me. Because to initiate a connection with a command like this, needs a long time, nearly 1 second, and the quality is poor (delay nearly more than 0.5 seconds and reverbation sound). So I tried it with pacmd-tool and the rtp-send-module, but I had some trouble with it, because I want only connect one or two hosts at the same time. Actually no problem with the parameter destination=?multicast address? (rtp-send....). But for this I have to install a router, where I can define the multicast adresses ?! It`s a good idea for big networks, but I have only few hosts in the same domain. Is there a possibilty to set the multicast adresses locally? You know a HOWTO? I also tried to set instead the multicast address the local host ip, but of course this doesn`t work (sendmsg() failed: in the rtp.c: and sap.c). This is pity because with this I had solved all my problems. Ideas for my problem are very welcome. thanks max p.s.: Pierres question in last mail. > > The second strange thing is that the Latency (I see it through -v) goes up to endless, or till I push CTRL-C. > > > >Pierre: This shouldn't happen though. Can you check the latency on "out" when this happens? The latency of the "out"-modules is normal, I thing it was the prob with incompatible data. -- "Ein Herz f?r Kinder" - Ihre Spende hilft!
