  /*
   * This OpMode demonstrates how to play simple sounds on both the RC and DS phones.
   * It illustrates how to build sounds into your application as a resource.
   * This technique is best suited for use with Android Studio since it assumes you will be creating a new application
   *
   * If you are using OnBotJava, please see the ConceptSoundsOnBotJava sample
   *
   * Use Android Studio to Copy this Class, and Paste it into your team's code folder with a new name.
   * Remove or comment out the @Disabled line to add this OpMode to the Driver Station OpMode list
   *
   * Operation:
   *
   * Gamepad X & B buttons are used to trigger sounds in this example, but any event can be used.
   * Note: Time should be allowed for sounds to complete before playing other sounds.
   *
   * For sound files to be used as a compiled-in resource, they need to be located in a folder called "raw" under your "res" (resources) folder.
   * You can create your own "raw" folder from scratch, or you can copy the one from the FtcRobotController module.
   *
   *     Android Studio coders will ultimately need a folder in your path as follows:
   *       <project root>/TeamCode/src/main/res/raw
   *
   *     Copy any .wav files you want to play into this folder.
   *     Make sure that your files ONLY use lower-case characters, and have no spaces or special characters other than underscore.
   *
   *     The name you give your .wav files will become the resource ID for these sounds.
   *     eg:  gold.wav becomes R.raw.gold
   *
   *     If you wish to use the sounds provided for this sample, they are located in:
   *     <project root>/FtcRobotController/src/main/res/raw
   *     You can copy and paste the entire 'raw' folder using Android Studio.
