Iphone 13 pro max ringtone not working from bottom speakers
I have an iPhone 13 pro max and the ringtone audio is not working from the bottom speakers.
All other audio works fine from the bottom speaker such as watching videos from photos or YouTube, but when I get an incoming call or if I go to the sounds & haptic in settings to change the ringtone/volume, audio output can only be heard from the top speakers.
I have tried to troubleshoot options I've read, such as making sure Do Not Disturb is off, turned off max volume settings and preformed a hard reset, but nothing has fixed the issue.
The iPhone 13 pro max is current on the lasted IOS 18.3.1.
