Based on: https://stackoverflow.com/questions/31692577/how-to-play-audio-through-built-in-earpiece-speaker

Works nicely.

Sub Class_Globals
    Private Root As B4XView
    Private xui As XUI
    Private VideoPlayer1 As VideoPlayer
End Sub

Public Sub Initialize
End Sub

'This event will be called once, before the page becomes visible.
Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
    Me.As(NativeObject).RunMethod("addProximityMonitor", Null)
    VideoPlayer1.LoadVideoUrl("https://stream-dc1.radioparadise.com/mp3-32")
    VideoPlayer1.Play
End Sub

#if OBJC
- (void)addProximityMonitor {
    AVAudioSession* audioSession = [AVAudioSession sharedInstance];
    [audioSession setCategory:AVAudioSessionCategoryPlayAndRecord error:nil];
    [audioSession setActive:YES error:nil];

    AVAudioSessionPortDescription *routePort = audioSession.currentRoute.outputs.firstObject;
    NSString *portType = routePort.portType;

    NSLog(@"PortType %@", portType);

    if ([portType isEqualToString:@"Receiver"]) {
        [audioSession  overrideOutputAudioPort:AVAudioSessionPortOverrideSpeaker error:nil];
    }
    [UIDevice currentDevice].proximityMonitoringEnabled = YES;
    if ([UIDevice currentDevice].proximityMonitoringEnabled == YES) {
        [[NSNotificationCenter defaultCenter] addObserver:self

                                               object:[UIDevice currentDevice]];
    }
}

- (void) proximityChanged:(NSNotification *)notification {
    UIDevice *device = [notification object];
    NSLog(@"In proximity: %i", device.proximityState);
    AVAudioSession* audioSession = [AVAudioSession sharedInstance];
