+         The device pre/post processor configuration is described in a deviceEffects element and
+         consists in a list of elements each describing pre/post processor settings for a given
+         device.
+         Each device element has a "type" attribute corresponding to the device type (e.g.
+         speaker, bus), an "address" attribute corresponding to the device address and contains a
+         list of "apply" elements indicating one effect to apply.
+         If the device is a source, only pre processing effects are expected, if the
+         device is a sink, only post processing effects are expected.
+         The effect to apply is designated by its name in the "effects" elements.
+         The effect will be enabled by default and the audio framework will automatically add
+         and activate the effect if the given port is involved in an audio patch.
+         If the patch is "HW", the effect must be HW accelerated.
+         Note:
+         -Device are not expected to be always attached. It may be loaded dynamically. As the device
+         effect manager is getting called on any audio patch operation, it will ensure if the given
+         device is involved in an audio patch and attach the requested effect.
+         -Address is optional. If not set, the match to instantiate the device effect will be done
+         using the given type and device (of this type) with empty address only.
