Hi Chris, The audio file itself is still there, but the flash player isn't. Apparently, when a post is created with the updated audio module and/or using the new flash player, the audio must be produced with a a sample rate of 11, 22, or 44khz. In Audacity, Edit/Preferences/Quality will allow you to change this setting. Personally, I'm not aware of any way to convert an existing audio clip to a different sample rate, other than playing it in media player and re-recording it with the required settings.
