Need help with using OPUS over RTP

Hi, I'm currently trying to get as low latency as possible for audio over my
Ethernet LAN. So I found out about OPUS (formet CELT) and have been trying
to use it. 

I can stream the test sound if I do like this:

Client:
 gst-launch-0.10 audiotestsrc ! audioconvert ! opusenc ! rtpopuspay !
udpsink host=reciver port=5000

Reciver:
AUDIO_CAPS="application/x-rtp,media=(string)audio,clock-rate=(int)48000,encoding-name=(string)X-GST-OPUS-DRAFT-SPITTKA-00

gst-launch-0.10 udpsrc caps=$AUDIO_CAPS port=5000 ! rtpopusdepay ! opusdec !
alsasink


I've problems with streaming other from ex pulsesrc. Should I convert it to
a WAV format before sending it to opusenc ? Yeah, a push in the right
direction would be nice :) 


Thanks
Envion
