Hi Homerj222,
Thanks for using Apple Support Communities! I see you're having an issue with the alarm and ringer volume on your iPhone, and I'd like to do what I can to help.
Have you restarted your iPhone since noticing this issue? If not, go ahead and do that, as a restart can resolve unusual issues.

Take care!
