     * Allow or disallow use of Bluetooth A2DP for media.

     * <p>The default behavior of the system is to use A2DP for media playback whenever an A2DP sink

     * is connected. Applications can use this method to override this behavior.

     * Note that the request will not persist after a wired headset or an A2DP sink is connected or

     * disconnected:

     * - Connection of an A2DP sink automatically enables use of A2DP.

     * - Connection of a wired headset automatically disables use of A2DP.

     * - Disconnection of a wired headset automatically enables use of A2DP if an A2DP sink is

     * connected.

     * <p>Requires Permission:

     *   {@link android.Manifest.permission#MODIFY_AUDIO_SETTINGS}.

     * @param on set <var>true</var> to allow use of A2DP for media (default).

     *               <var>false</var> to disallow use of A2DP for media.

     * @param on set <var>true</var> to route A2DP audio to/from Bluetooth

     *           headset; <var>false</var> disable A2DP audio

     * @deprecated Do not use.
