Okay so I finally figured this out for those who use music for their alarm. The alarm will not play a song if it was downloaded in lossless audio format. Remove the download you want to use from your library and then download it again after switching the audio quality setting to “high quality” under music settings. You can then switch it back. Just make sure that the song you are trying to use for your alarm wasn’t downloaded in the lossless format.


When I try to use a song in lossless format, I get no sound and no vibrate but when I use a song downloaded in high quality, I get both sound and vibrate. Odd but try it yourself and hopefully that works for you as well.
