The CORK request is not reaching to the client (gst pulse-sink in this case). 

Please check the GST Logs for "music" stream in two different scenarios below:

(I have kept prints for ENTRY/EXIT/CORK/UNCORK in
gst_pulsering_stream_event_cb() function )


I. 
Playback first music stream and then phone stream arrives: Works fine and we
are getting CORK request for music stream.

# gst-launch playbin2 uri=file:///userdata/media/phone/Music/Raindrops.mp3
audio
-sink="pulsesink role="music""
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
DBG: pa_stream_new_with_proplist: 99: name = Playback Stream
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstPulseSinkClock

 gst_pulsering_stream_event_cb: ENTRY

 gst_pulsering_stream_event_cb: got request for CORK
Setting state to PAUSED as requested by

^CCaught interrupt -- handling interrupt.

II. 

Playback Order: Phone stream already ongoing and then Music stream starts: the
streams were getting mixed, We are NOT getting CORK request here.
  Getting "got request for UNCORK" after killing "phone" stream.

# gst-launch playbin2 uri=file:///userdata/media/phone/Music/Raindrops.mp3
