GStreamer audio streaming on Windows

I'm experimenting a bit with GStreamer (ossbuild 0.10.7) on Windows, but I can't seem to make audio streaming between two computers work. All I hear at the receiver side is a short beep followed by silence.

This is the sender pipeline:

gst-launch -v audiotestsrc  ! audioconvert ! rtpL16pay ! udpsink host=224.0.0.7 auto-multicast=true port=4444

This is the receiver pipeline:

gst-launch -v udpsrc multicast-group=224.0.0.7 port=4444 caps="application/x-rtp, media=(string)audio, channels=(int)1, clock-rate=(int)44100, encoding-name=(string)L16" ! gstrtpbin ! rtpL16depay ! audioconvert ! queue ! autoaudiosink

I've already tried different queue settings and codecs. Same thing when I try to stream an audio file, all I hear is about 1 second of it. What could be the problem?

Appears to be a problem with autoaudiosink and rtpL16. This pipeline works:

Sender: 

gst-launch -v directsoundsrc ! audioresample ! audio/x-raw-int, rate=8000 ! audioconvert ! udpsink host=224.0.0.7 port=4444

Receiver:

gst-launch -v udpsrc multicast-group=224.0.0.7 port=4444 caps="audio/x-raw-int, channels=(int)2, rate=(int)8000, width=(int)16, depth=(int)16" ! audioconvert ! directsoundsink

This pipeline also works:

Sender:

gst-launch -v directsoundsrc ! audioresample ! audio/x-raw-int, rate=22000 ! faac ! audio/mpeg,mpegversion=4  ! rtpmp4apay ! udpsink host=224.0.0.7 port=4444

Receiver:

gst-launch -v udpsrc multicast-group=224.0.0.7 port=4444 caps="application/x-rtp, channels=(int)2, clock-rate=(int)22000, encoding-name=(string)MP4A-LATM, config=(string)40002410" ! gstrtpbin ! rtpmp4adepay ! faad ! directsoundsink
