Add support for soundmanager2?

Yes those 2 functions are all you need. Basically you just need to paste embedd code of Soundmanger in 2nd function and replace some arguments with php variables as in given example.

It would be best if the guys at Soundmanager add this to their module, implementing audiofield hooks. This way they could focus on Soundmanager UI, while the background work will be done by Audiofield.

Does it work now?

Don't think they implemented it yet. You can ask Soundmanager module maintainers at http://drupal.org/node/1146172

The sound manager 2 module is pretty quiet... However I see in the repository viewer that SM2 functionality has been added to the 6.x version of audiofield, will it be coming to the d7 version too then?

Yes it will be ported to D7 in the coming days.

Voilà... a patch.

It can be better.. using theme function and so. But it works and should be pretty easy to improve.

I also added what I said in #1468796: Send the field to the players so we can display the file's title so I can display the file title.

I also add $settings360 but no time for a patch right now...

function audiofield_soundmanager2($player_path, $audio_file,$variables) {
  static $instanceIndex = 0;
  if ($audio_file == '') {
    return t('HTML5 media player for soundmanager2 (skin 360-player)');
  }
  else {
    $instanceIndex += 1;
    if (!empty($variables['file']->description)) {
      $filename = $variables['file']->description;
    }
    else {
      $filename = $variables['file']->filename;
    }
    //Add JS files and settings only one time
    if ($instanceIndex == 1) {

      $player_base_path = variable_get('audiofield_players_dir', 'sites/all/libraries/player') . "/soundmanager2";
      $ie_js = array(
        '#type' => 'markup',
        '#markup' => '<!--[if IE]><script type="text/javascript" src="' . $player_path . '/demo/360-player/script/excanvas.js"></script><![endif]-->',
      );
      drupal_add_html_head($ie_js, 'audiofield');
      drupal_add_js($player_base_path . '/script/soundmanager2-nodebug-jsmin.js');

      //360 viewer 
      drupal_add_js($player_base_path . '/demo/360-player/script/berniecode-animator.js');
      drupal_add_js($player_base_path . '/demo/360-player/script/360player.js');
      drupal_add_css($player_base_path . '/demo/360-player/360player.css');

      $settings = 'soundManager.url = "' . $player_path . '/swf"; // directory where SM2 .SWFs live
        soundManager.useFastPolling = true; // increased JS callback frequency, combined with useHighPerformance = true
        soundManager.waitForWindowLoad = true;

        //so Firefox and others without MP3 support work 
        soundManager.preferFlash = true;

        // disable debug mode after development/testing..
        soundManager.debugMode = false;
        soundManager.onready(function () {
          soundManager.stopAll();
          threeSixtyPlayer.init();   
        });';
      drupal_add_js($settings, array('type' => 'inline', 'scope' => 'header'));
      $settings360 = "threeSixtyPlayer.config = {
              playNext: false, // stop after one sound, or play through list until end
              autoPlay: false, // start playing the first sound right away
              allowMultiple: false, // let many sounds play at once (false = one at a time)
              loadRingColor: '#ccc', // amount of sound which has loaded
              playRingColor: '#000', // amount of sound which has played
              backgroundRingColor: '#eee', // 'default' color shown underneath everything else
              animDuration: 500,
              animTransition: Animator.tx.bouncy // http://www.berniecode.com/writing/animator.html
           }";
      drupal_add_js($settings360, array('type' => 'inline', 'scope' => 'header'));
    }

    return ' 
    	<div id="sm2-container-real" class="ui360">
        <a href="' . $audio_file . '">' . $filename . '</a>
    	</div>';
  }
}

I'm getting the following errors with the updated code posted in #7:

Warning: Missing argument 3 for audiofield_soundmanager2() in audiofield_soundmanager2() (line 211 of C:\Users\Ben\Sites\acquia-drupal\sites\all\modules\audiofield.players.inc).

You have to use the patch #6 first and after replace the function.

Needs work due to a latest bug fixes & patches applied.

7.x version allows for the use of Sound Manager 2. See issue #2615240: Soundmanager 2 Players for discussion on adding additional Sound Manager 2 players.
