# 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
