Please tell us some basic information before asking for help:

========================================
I am trying to change my alarm tone. But even after changing it in the settings, the change wont take effect. Already tried clearing the cache, restarting my phone, changing it again, running the alarm, but it is still the old alarm tone that is playing.

Hi dj.mics
Thank you for your asking. I didn't encounter the same situation with my device in the same firmware. Kindly try some stay-at-home troubleshooting tips below:
1. Please make sure that you put the music clip into "Alarms" file
2. Please try to enter "Safe Mode". If the function works well in Safe Mode yet the issue remains out of Safe Mode, please check on any disturbance from the installed 3rd party apps.

3. Also, please try "the Factory Reset" 
Settings>System>Reset options>Erase all data(factory reset)
Please note that once the Factory Reset is completed, all data, apps, settings and personal information will be deleted.
4. Have you ever rooted or unlocked your device before?
5. If the situation remains after performing the factory reset, please provide me a video of your alarm setting process for further checking.
