Looks like I found a solution. According to the documentation, the volume of AVAudioPlayer can be between 0.0 and 1.0. Apparently, it can be set to a value greater than 1.0. By increasing the volume, I was able to achieve the same desired result. Until it normalizes, the gain increases.

#import <AudioToolbox/AudioServices.h> UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker; AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute, sizeof (audioRouteOverride),&audioRouteOverride);

It will play your sound in speaker mode.
