No ringtone for Calls, iMessages, & Text Messages on iPhone 16 Pro Max

Is anyone having an issue with their iPhone 16 Pro Max not sounding off alert notifications… i.e. iMessages, text messages, or even incoming phone calls. My phone receives the messages and calls but never notifies me by my music ring tone sound. I already turned off my focus just to see if that was what was causing the issue, but I still am not receiving my ring tone music sound. I have already restarted my iPhone several times too. Please advise.
