Cannot use music for alarms on iPhone 14

Have you tried playing the music you want to use through the Music app? I wonder if perhaps it hasn't been completely downloaded?

Beyond that, I don't have much to suggest. I never use music as my alarm tone as it's a feature that has always been a bit finicky.

Same here. I found a workaround by selecting a song in my library that was not lossless. That works.

I also needed to download the song to my phone before it would work as an alarm. Alarms will only use music that has been downloaded to your device. Stupidly, the app let you select music that has not been downloaded so there’s no way to tell that this is required.

I have heard of others deleting the lossless song they were trying to use, going into settings and turning off lossless as well as Dolby, then re-downloading the song in high quality rather than lossless. Then they go back in and turn lossless and Dolby back on again for future use.

Seems like Apple might try a bit harder to fix this bug. I suppose first they need to acknowledge it, which they’ve never done.

Try deleting the alarm and re-adding it.

If you have the mp3 file for the song you can import it into GarageBand and set it as a ringtone.
