+# 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
