There seem to be a very specific bug in the current version of flowplayer audio plugin. Upon attempt to play the file over https in Chrome or IE, the player controls become broken in a way that clip duration is not shown, navigation slider is not functioning and pause button does not work. This is only applicable to audio content (handled by flowplayer plugin /lib/flowplayer/flowplayer.audio-3.2.2.swf), the video content accessible over https link works fine.

This is the case for both File resource and media-plugin filter, as they both use the same M.util.add_audio_player method for initiating the player.

The issue appears in Chrome 15.0.874.106 and IE 8, works fine with Iceweasel 7.0.1 and FF 8.0.

To replicate, if your site is hosted via https, create a file resource to any mp3 file and observe the issue. Alternatively you may add a link to audio file hosted remotely over https to the Page resource.

There seem to be a related bug already reported upstream, but the suggested fix does not solve the problem.
