• How to play sounds (rightly) in games?

  Hello

  What is the correct way to play a sound effect in a game (or any application using a wire loop). I use a method that works very well on 99% of the phones, but it seems to cause a small number of phones for my client to freeze after a few sounds in game (I guess it's sort of leak memory). I also noticed that it creates an error in my event log (StreamingException: not logged in net.rim.device.internal.streamingnatives), even if the game continues to function normally.

  Obviously something is wrong, but I can't understand what it is. Here is the code I use:

  SoundObject.java:

  public class SoundObject {
      Player player;
      VolumeControl vc;
  
      public SoundObject(String res) {
          Class cl = null;
          try {
              cl = Class.forName("my class path goes here");
          } catch (ClassNotFoundException e) {
              e.printStackTrace();
          }
  
          InputStream input = null;
          try {
              input = cl.getResourceAsStream(res);
              player = Manager.createPlayer(input,"audio/mpeg");
              player.realize();
              player.prefetch();
              vc = (VolumeControl) player.getControl("VolumeControl");
          } catch (Exception e) {
              e.printStackTrace();
          }finally{
              try {
                  if(input != null){
                      input.close();
                      input = null;
                  }
              } catch (IOException e) {
                  e.printStackTrace();
              }
          }
      }
  
      public void setVolume(int val){
          try{
              if(this.vc != null){
                  vc.setLevel(val);
              }
          }catch(Exception e){
              e.printStackTrace();
          }
      }
  
      public void Play(){
          if(Settings.getSoundVolume() == 0) return;
          try {
              if(player != null){
                  player.stop();
              }
              player.start();
          } catch (Exception e) {
              e.printStackTrace();
          }
      }
  }
  

  To load the sound I do the following:

  public static SoundObject sound_boing = new SoundObject("/boing.mp3");
  sound_boing.setVolume(50);
  

  And in the thread of my game, I play the sound like this:

  sound_boing.Play();
  

  Can someone tell me what I'm doingwrong? Copy the following code causes a memory leak? Y at - it a particular format of the audio file I should avoid? This could be the cause of the StreamingException: Session not open error?

  Thank you!

  Hi Dekerta!

  If I read your code correctly you are creating an InputStream to a sound file, and then close the stream before playing what seems to be the problem.  Calling prefetch below will read the InputStream and pre-load the player with data - if the file is small enough (which I am assuimg that yours is) then it can indeed read the entire file in the stream.

  The essential point that you don't know, is that this loading is made asynchronously.  As you close the stream your finally block you introduce a race condition - if it finally is executed before the player is first read then you will get the Exception you see (the stream is not open because you closed it).  If the player completes the preloading before closing the flow then the sound will play, which seems to be the case for 99% of the time .

  Rather than close the stream immediately, why not keep it open until the player becomes closed in this way it is always available for the player and is no longer available when you can be sure that the player no longer has need you can save it to a field in your SoundObject and close in a PlayerListener implementation when you get the event PlayerListener.CLOSED

  As alternative approach to play 'unique' sounds, check on the sample inthe pos , it is optimized for work for the CDMA and GSM-based devices universally, all keeping as minimal as possible use of the resources and the most effective cleaning possible.  The only other approach I've used that works well is to mix your own sounds, but I won't get it here since it is a topic all by itself (although the DEV04 session of the Conference DevCon2010 in recent years tells you how... just saying ' ).

• How to play sound loop

  Hello

  How can I play looping sound? Is it just well SoundChannel class responsible for this or I have to write my own function?

  With the help of the sound object, there is a property, you can move that asks the number of loops of

  Play (StartPosition:Number, Loops:int, SoundTransform)

  or you can create your own method who listens SoundComplete and then starts playing again.  which in my opinion is the best thing to do because when you play a sound with a loop and choose to have is to start at a different position of 0 so the loop will play from where you set the position.

• How to play sound in AS3

  In AS2, you can listen to sound through s.loadSound("mysound.mp3",true) where the second loadSound parameter indicates that you want the sound.
  How do you do this in AS3?
  Thanks for your help.
  Ken

  When you run your load(), the audio file begins to download. who will continue unless you run a close() method.

  your sound will start playing when you run, you're your play() method or after the bufferTime is met, the first of the two prevailing.

  the real question is how do you keep streaming in as3. and who is easy to aid sound complete event to trigger the play() method. If the play() method is executed while loading is complete AND bufferTime is lower than the charging time, your sound will flow.

• Play sounds in the order using MediaPlayer

  Hello. How to play sounds in order?

  For now, here are my code.

  I have a MediaPlayer component as an attached object

  http://developer.BlackBerry.com/native/reference/Cascades/bb__multimedia__mediaplayer.html

  attachedObjects :[
      MediaPlayer{
         id: sound
         sourceUrl: "asset:///sounds/sound1.mp3"
      }
  ]
  

  Then I have a button. Here is what my code for it

  Button{
     id: play
     text: "Play Sequence"
  
     onClicked :{
  
        sound.sourceUrl = "asset:///sounds/sound1.mp3"
        sound.play();
        sound.sourceUrl = "asset:///sounds/sound2.mp3"
        sound.play();
        sound.sourceUrl = "asset:///sounds/sound3.mp3"
        sound.play();
  
     }
  }
  

  What goes wrong.

  The code runs after 1 second about, cut the next sound. I'm doing his next game, after the end of his previous.

  

  The sounds are not finished because play() is not a call blocking. Once you call the play() function it will start playing the sound and return immediately to the following line of code in the QML. If the next line is a call to the play() still it will have precedence over previous sound, i.e. If you think logically about what you need in an application, you would not have the sound of a doorbell 2 seconds later, play just because you play already a sound, you would stop, as it does.

  My suggestion to use a selection intended to use the MediaPlayer playlist function, that you implemented will obviously suffer from the same problem for the above reason. A playlist is a separate file that contains a list of media you want to play and can be in different formats.

  My other suggestion of using onPlaybackCompleted does not seem to have been followed by you, but is probably the easiest to implement.

  MediaPlayer {
      id: mediaPlayer
  
      onPlaybackCompleted: {        count = count + 1;
          var s = count;
          mediaPlayer.setSourceUrl("asset:///sounds/sound" + s + ".mp3");
          mediaPlayer.play();
      }
  
  }
  

  Where count is a comprehensive, defined property to 1 in your QML file and you have some relaxation (onCreationCompleted or clicking a button) to start the first play().

• How to make sound to play through my headphones and not my TV when you use an HDMI cable to extend my desktop?

  Often, I connect my laptop to my TV to extend my desktop and find work more quickly. Today, I wanted to listen to music then I worked, but did not want to disturb others in the House with the sound so I plugged my headphones on my laptop but the sound plays through television. How can I get it to play through my headphones only?

  I do not use HDMI but audio HDMI runs your graphics instead of the audio chip

  the laptop, so I think that you can turn off the HDMI audio in your graphics cards

  The control panel settings.

  -If not, you should be able to disable the HDMI audio via Device Manager.

  The HDMI audio will probably be known as your graphics (Nvidia, AMD or Intel).

  [Type Device Manager in the search bar on the Start Menu and select - sound, video and game controllers.] R / click on the appropriate audio device and select disable. ]

  Or - connect your headphones to the TV should turn off the sound from the speakers.

  You can purchase an extension for headphones, if necessary.

• How to fix sound coming speakers and headphones at the same time?

  My computer old enough, I'll tell you that. I bought it on ebay with Windows XP pre-installed, and I uninstalled it instantly to I can have the pleasure of installing Windows Me (because I'm a little strange) with an installation disc, I had to hang out. Everything worked fine, until one day I decided to install Windows NT 4.0 and that pretty well done the sound somehow. To resolve this problem when I reinstalled XP, I found a driver that worked perfectly. With XP, I've had no problem with the sound since I installed the driver; the sound comes through the headset when it is plugged and through the speakers when my headphones are plugged into.

  Now, here's the problem. I installed Windows 7 Home Premium last night, as it came with another computer that broke some time ago. It works perfectly, just a little slow because my computer is old. Of course, I expect to have to install the audio driver again, as I formatted my hard drive before installing 7. So I downloaded the driver from the same place, as I always do, site Web of Realtek. After installation, the sound works fine - but it comes out through the speakers and the headphones at the same time.
  I tried to plug my headphones into the Jack located on the front of the computer and back, and it's still having the same problem. He has nothing else connected to the computer but the monitor, keyboard, mouse and wifi adapter.
  Windows 7 is the only OS by far that has had this problem on this computer. Strangely, on the computer on which he came with, I have no trouble. I plugged it right in there and badabing badaboom, everything was perfect.
  So I don't understand why it does not work on this computer. If necessary, my audio device in the sound options is Realtek AC 97 Audio.
  Any help would be appreciated!

• Pavilion DV4: Laptop plays sound through headphones but not by internal speakers

  Audio was working fine on my laptop, when suddenly the laptop would not play sound with internal speakers.  If I plug in headphones sound is fine.  Execution of control panel of configuration/sounds shows 'Speakers and dual headphone - IDT High Definition Audio CODEC' enabled and set as the default device, as well as "independent double headphones" (enabled by default but not) and 'SPDIF (Digital Out via HP docking station)' disabled.  What can be wrong?

  Cure the problem by uninstalling the CODEC driver, then restart Windows then reinstalled, and now things are ok again.
