You can use MediaPlayer to play it. It will allow you to change the volume.

You need to set the audio session each time after you finish recording.

B4X:

Sub SetAudioSession
 Dim no As NativeObject = Me
 no.RunMethod("setAudioSession", Null)
End Sub

#if OBJC
#import <AVFoundation/AVFoundation.h>
#import <AudioToolbox/AudioToolbox.h>
- (void)setAudioSession {
   AVAudioSession *audioSession = [AVAudioSession sharedInstance];
   NSError *err = nil;
   BOOL success = [audioSession setCategory:AVAudioSessionCategoryPlayback error:&err];
   if (success) {
     success = [audioSession setActive:YES error:&err];
   }
   if (!success)
     [NSException raise:@"" format:@"Error setting audio session: %@", err];
}
#end if
