+# Author: Fulup Ar Foll
+# Object: PCM hook type
+#
+# Test : Note: Jabra_USB=hw:v1340
+# Check SoundCard ==> speaker-test -Dhw:v1340 -c2 -twav
+# Check MixerPCM ==> speaker-test -DSpeakers -c2 -twav
+# Check SoftVol ==> speaker-test -DMusicPCM -c2 -twav
+# Check Plugin ==> speaker-test -DMultimedia -c2 -twav
+# Check Plugin ==> speaker-test -DNavigation -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
