Sorry about the delay here, I've been swamped with other things recently and not had as much time to spend on this project as I've wanted to. As far as the no sound playing goes, have you tried it with one of the default MP3s that comes pre-loaded on the tablet? Try setting the alarm for like 2 minutes ahead of the current time and then see if it actually plays and does the alarm thing.

Also try the same thing from X-term; that is, run flipclock, then set an alarm for a minute or two in the future and wait for it to go off. Once it's started/alarming then stop it by pressing the screen, exit flip, and post up the x-term output as I'm pretty sure I left the debugging stuff for the actual alarm playback in there by default.

Failing that I'll setup a backport build so that I can make some small tweaks to the existing app (the current development build is VERY different from the existing app in terms of the way the coding works) so that we can try and get things sorted out for you.

Thanks!
