With hardy and Pulseaudio 0.9.10 I am having trouble lowering the buffer of the rtp-recv module. This is not a big deal if I did not also use the LOOP parameter with rtp-send module. Because then the latency of >100ms is a bit disturbing. The loop is there because in my application it is required that speaker also hears himself and also it makes it easier to record a conversation of several people. Could the loop be made so that it would not go through the rtp-module?

Isn't this LATENCY_USEC only in versions >0.9.10? There is no 
corresponding setting for 0.9.10? Another question, is it possible to 
split the stream from source to both rtp-send and local sink?
