#
# Mixer kcontrol class. All attributes defined herein are namespaced
# by alsatplg to "Object.Control.mixer.N.attribute_name"
#
# Usage: this component can be used by instantiating it in the parent object. i.e.
#
# 	Object.Control.mixer."N" {
#		index	1
#		name	"1 Master Playback Volume"
#		mas 32
#			Object.Base.channel."fl" {
#				shift	0
#				reg 0
#			}
#			Object.Base.channel."fr" {
#				shift 1
#				reg 1
#			}
#			Object.Base.ops."ctl" {
#				info "volsw"
#				get "258"
#				put "258"
#			}
#	}
#
# Where N is the unique instance number for the buffer object within the same alsaconf node.
# The mixer control object should also include the ops, channels and tlv objects in the object
# instance
