Modifiers are an extra layer on top of devices. I don't think that we have any default relation between the modifier PCM device and the original PCM device (from the UCM device definition). A new value to describe this (like "ReplacePlaybackPCM 1") may be introduced. Another issue is when multiple modifiers with this description are active - they conflict, so it should be described somewhere, too. Perhaps, "ConflictingModifier" array may be added to API. But those extensions are not required for the "Echo Reference" modifier.
What is the expectation for naming and relationship to the devices? Is the Modifier a suffix to the device name to associate it?
