# A generic SRC component. All attributes defined herein are namespaced

# Usage: this component can be used by instantiating it in the parent object. i.e.
#
# 	Object.Widget.src."N" {
#		format			"s24le"
#		rate_out		48000
#	}
#
# Where N is the unique instance number for the src widget within the same alsaconf node.
