+Subject: [PATCH] Fix issue: there is no sound after plugin/plugout headphone
+
+In default config, when switching headphone with speaker, the unused one will
+be switch off. And pulseaudio will store the setting in the database for
+restore later, when switch back to the output path.
+But the core-subscribe.c has a defer queue for these events, like sink|new,
+sink|change, which will read the current switch status and store it in
+the database. Because it is a defer queue, sometimes the stored status is
+changed not as user's requirement. below is the call flow.
+
+init:
+        store on for speaker to database.
+        store on for headphone to database.
+---Activating analog-output-speaker
+	switch on speaker
+	switch off headphone
+----headphone plugin
+   ---analog-output-speaker status no
+   ---Activating analog-output
+      Queued event (SINK|CHANGE|0)
+      switch off speaker
+      switch off headphone
+   ---analog-output-headphone status yes
+   ---Activating analog-output-headphone
+      switch off speaker
+      switch off headphone
+      Dispatched event (SINK|CHANGE|0)
+       store off for headphone to database.
+
+Meantime the root cause is not found, a workaround is used by changing the
+configure file.
+
+Another change is remain the volume same as the asound.state.
+
+Upstream Status: N/A
+  - It is i.Mx specific
