One of my students just gave me a piece of information that might help to solve this problem. She noticed that she could hear the audio on one page on my site, but not another. She is running the latest version of Flash.
The page that is working was last edited in 2006 under Moodle 1.5. The page where the audio isn't working was last edited on March 31 under Moodle 1.6.5. So I looked at the code that was on each page (in editing view), and notice a difference. Here's the code on the page that is working:
<a href="http://www.glyphdoctors.com/file.php/8/audio/a.mp3"> </a></div><param value="http://www.glyphdoctors.com/filter/mediaplugin/mp3player.swf?src=http://www.glyphdoctors.com/file.php/8/audio/a.mp3" name="movie" /><param value="high" name="quality" /><param value="#333333" name="bgcolor" /> <param value="bgColour=000000&btnColour=ffffff&btnBorderColour=cccccc&iconColour=000000&iconOverColour=00cc00&trackColour=cccccc&handleColour=ffffff&loaderColour=ffffff&waitForPlay=yes" name="flashvars" />
Here's the code on the page that isn't working:
<a href="http://www.glyphdoctors.com/file.php/8/audio/2.6/A.mp3"> </a>
So basically what is going on is that the simple version of code doesn't work with the latest version of Flash. Oddly enough, the code looks the same to me in the actual output on the page. But I may be missing something.
I've manually edited the code on the page that isn't working to add the extra stuff and the players are now playing the sound, so Moodle needs to be made to put in the full code I guess.
I'd just like to add that this problem is going to become more and more widespread as Flash players automatically update in more and more users' browsers and become incompatible with Moodle. I've had two students (and myself) with this problem in the last few days. Downgrading is only a temporary option. I've already come across other sites that don't work with the downgraded version and even if we downgrade, Adobe will automatically upgrade us again.
