+# Object: PCM hook type 
+#
+# Test  :  Note: Jabra_USB=hw:v1340
+#  Check SoundCard  speaker-test -Dhw:v1340 -c2 -twav
+#  Check MixerPCM   speaker-test -DMyMixerPCM -c2 -twav 
+#  Check HookPCM    speaker-test -DMyNavigationHook -c2 -twav

+#  MultiMedia aplay -DDMyNavPCM /usr/share/sounds/alsa/test.wav
+#
+# Bug/Feature: when softvol control is initialised from plugin and not
+#    from AGL binding. At 1st run ctl has invalid TLV and cannot be
+#    use. Bypass Solution: 
+#     * start audio-binder before playing sound (binding create control before softvol plugin)
+#     * run a dummy aplay -DMyNavPCM "" to get a clean control
