How to fix silent alarm issue after iOS update on iPhone 15 Pro and Apple Watch Series 10?

Same issue here I leave my phone on silent/DNS but still need my alarms to go off and vibrate with notifications. Simple fix that I did not expect to have to do. Go to settings>>sounds and haptics>>ringtones and alerts. If you are like me, the volume is already all the way up. To fix issue you have to actually move the volume to play a sound, reminding the phone this is what the user wants and at this volume. You can then put back to max volume and problem should be fixed. Worked for me with alarms, but spam calls have not roled in yet to know if it fixed the vibrating while on silent mode. Hope this helps everyone! Update, phone also vibrates when getting calls.

I ended up calling Apple support this morning and they said they’ve had several calls regarding the alarm issue so sounds like a bug in the new operating system. She said the engineers are looking into it so hopefully there will be a fix soon.

In regards to the podcast issue (endless buffering), seems as if I was the first one to call about it but it must also be because of the new operating system. I’m also waiting for a bug fix for that.

It's not always the iOS update's fault!  Many things can cause phone problems.  If you tell people you think it's an iOS update, it might make it harder to fix or find a solution for the real issue.

Remember, the right question often leads to the solution!

Was/Is your device Jailbroken? If that's the situation, please be informed that attributing the issues to iOS updates may not be accurate.

iOS updates aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. The majority of the issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.

Kindly consider checking your settings and addressing any device issues before attributing the issue to external factors. This could be a pure coincidence that the iOS update affected the iPhone functions.

Before initiating a standard iOS update, it's advisable to create a backup. Have you completed this step? If yes, proceed with the restoration from the backup.

HELP! Downloaded the newest operating system last night. My alarm didn’t make a sound this morning, although once I woke up the screen appeared as if the alarm was going off, and I overslept. I just tried the above suggestions but still can’t get the alarm to make a sound, even with silent mode off. It’s still silent as can be, although on the screen it appears to be going off. I have an early morning flight coming up and need my alarm to actually “alarm”!!! I think Apple needs to do a fix ASAP!
