After updating from 0.9.6 to 0.9.7-4, when the alarm fires, it plays for a few seconds (about 3 seconds) and then suddenly stops. When the alarm sound stopped playing (I designated a specific song for the alarm), the screen still correctly shows the two buttons (Alarm off and snooze) and responds as expected.

To reproduce, if I set the alarm 1 minute later from the current time, it plays well though. Can someone help me solve the problem? It's not easy to reproduce, but the problem happens on every morning ...
