I have the latest monthly Cyanogenmod 11 installed on my Samsung Galaxy SII phone. This past week, I noticed that the alarms I set (with both the built in alarm app and the I Can't Wake Up app from the Play Store) only ring once then goes silent (the alarm is still on the screen and the phone still vibrates). This is also true for incoming calls, the ringtone rings only once. I tried changing ringtones to no effect.
Looks like this is an issue that's not limited to a specific ringtone or app. How can I troubleshoot this? Thanks!
