It looks like the process will happen like this. This week or next Martin will finish Moodle version 1.2.1 and send it to Fantastico with his recommendation. Then Fantastico will send its upgraded pack to Netmondo. So if you can wait 1-2 weeks (possibly more), you can upgrade fairly automatically. That is what I will do because my site does not have any urgent needs. In your case, with classes starting up soon, and you need to use the embedded audio function, you might try my listed procedure. But be sure to have multiple backups of your data, and have time to sort out any problems.
