iPhone 12 alarms not sounding

For several weeks that my IPhone 12, IOS version 26.1 (and previous as I just updated it), fails to sound any alarm. I ended up setting two wake up alarms, one on "Sleep" and other on "Clock" with 5 minutes difference.

I don't care if the sound is on or off I need these alarms to go off! I can't thrust my Iphone anymore, what is really disappointing.

It cost me to get late to work today, and I had enough of this foolishness of having to fumble with settings, focus, sound level, set sound for the alarm and so on. And alarm is to go off unless you set if off!

This is ridiculous! Apple has to do something about it and fast!

MacBook Air 13″, macOS 15.6

If the alarm volume is too low or quiet

Do Not Disturb, the Ring/Silent switch and Silent mode don't affect the alarm sound. If you use the Ring/Silent switch or Action button to turn on Silent mode or turn on Do Not Disturb, the alarm still sounds.

If your alarm doesn't sound or is too quiet, or if your iPhone only vibrates, check the following:

Set the volume on your iPhone. If your alarm volume is too low or too loud, press the volume up or volume down button to adjust it. You can also go to Settings > Sounds & Haptics and drag the slider under Ringtone and Alerts.
If your alarm only vibrates, make sure your alarm sound isn't set to None. Open the Clock app, tap the Alarms tab, then tap Edit. Tap the alarm, then tap Sound and choose a Sound.
If you connect headphones to your iPhone, the alarm will play at a set volume through the built-in speakers on your iPhone as well as wired and wireless headphones.
When you use StandBy, haptics for your alarms are disabled. To make sure that your alarm sound isn't set to None: open the Clock app, tap the Alarms tab, then tap Edit. Tap the alarm, then tap Sound and choose a Sound.

Manually adjusting the time on your iPhone in Settings to change app behaviour, like game timers, isn't recommended and can affect alarms.
