+                   and output devices or between stream and devices.

+                 - <attachedDevices/>: permanently attached devices.
+                   The attachedDevices section is a list of devices names.
+                   Their names correspond to device names defined in "devicePorts" section.

+ * A channel mask per se only defines the presence or absence of a channel, not
+ * the order.
+ *
+ * The channel order convention is that channels are interleaved in order from
+ * least significant channel mask bit to most significant channel mask bit,
+ * with unused bits skipped. For example for stereo, LEFT would be first,
+ * followed by RIGHT.
+ * Any exceptions to this convention are noted at the appropriate API.
+ *
+ * AudioChannelMask is an opaque type and its internal layout should not be
+ * assumed as it may change in the future.  Instead, always use functions
+ * to examine it.
+ *
+ * These are the current representations:
+ *
+ *   REPRESENTATION_POSITION
+ *     is a channel mask representation for position assignment.  Each low-order
+ *     bit corresponds to the spatial position of a transducer (output), or
+ *     interpretation of channel (input).  The user of a channel mask needs to
+ *     know the context of whether it is for output or input.  The constants
+ *     OUT_* or IN_* apply to the bits portion.  It is not permitted for no bits
+ *     to be set.
+ *
+ *   REPRESENTATION_INDEX
+ *     is a channel mask representation for index assignment.  Each low-order
+ *     bit corresponds to a selected channel.  There is no platform
+ *     interpretation of the various bits.  There is no concept of output or
+ *     input.  It is not permitted for no bits to be set.
+ *
+ * All other representations are reserved for future use.
+ *
+ * Warning: current representation distinguishes between input and output, but
+ * this will not the be case in future revisions of the platform. Wherever there
+ * is an ambiguity between input and output that is currently resolved by
+ * checking the channel mask, the implementer should look for ways to fix it
+ * with additional information outside of the mask.

+-----------------------------------------------------------
+WHAT WAS *NOT* DONE, and you need to do now:
+ 1) You need to choose if the new HAL is optional or not for new devices.
+    Either add or replace $BASE_VERSION by $NEW_VERSION in
+    compatibility_matrices/compatibility_matrix.current.xml
+    Do not forget to update both the "audio" and "audio.effects" HAL'
+
+ 2) Then you need to choose a device to update its audio HAL implementation:
+    a) Update the HAL manifest of your device: open your device manifest.xml
+       and replace $BASE_VERSION by $NEW_VERSION for both
+        - android.hardware.audio
+        - android.hardware.audio.effect
+    b) Go to your device device.mk (usually next to the manifest) and replace:
+        - android.hardware.audio@$BASE_VERSION-impl by
+          android.hardware.audio@$NEW_VERSION-impl
+        - android.hardware.audio.effect@$BASE_VERSION-impl by
+          android.hardware.audio.effect@$NEW_VERSION-impl
