I was going to try the extends but the links to the Lenny Dev Extends are both 404. I set up PanDebian, and what it provides is cool, but it won't solve my current problem since all my searching around seems to confirm that no one has figured out how to get audio working with PanDebian. I guess I will just live with the compromise of Thunderbird with no audio and stick to using my Android devices as my main email device for a little longer until either a future update of Thunderibird gets audio or I get time to try porting IceDove or an html plugin for Claws.
