Pipeline, for reference:

gst-launch-1.0 playbin uri=file:///trailer.mov \
                       audio-sink=interaudiosink \
                       video-sink=intervideosink \
\
  audiotestsrc ! volume volume=0.1 ! audiomixer name=audiomix
caps='audio/x-raw,format=S16LE,channels=2,rate=48000' ! audioconvert !
pulsesink \
\
  interaudiosrc ! audioconvert ! audioresample ! audiomix. \
\
  intervideosrc ! compositor name=videomix
caps='video/x-raw,format=I420,width=1280,height=720,framerate=25/1,pixel-aspect-ratio=1/1'
! videoconvert ! xvimagesink


Adding queues after intervideosrc and interaudiosrc fixes it. "The audiotestsrc
seems to have a higher min latency than the interaudiosrc has as max latency"
