I am having trouble getting my flutter app to play audio through iOS speakers. I have tried on multiple iOS devices. The audio plays through android speakers, android headphones, and iOS headphones. I get no error messages about it, and the audio seems to be playing based on the log messages showing the position of the audio file changing.
I am using the package audioplayer (https://pub.dartlang.org/packages/audioplayer)
I have even tried running the example (https://pub.dartlang.org/packages/audioplayer#-example-tab-), and I get the same issue.
I have also tried using the package audioplayers (https://pub.dartlang.org/packages/audioplayers). Same thing. If anyone can point me towards any explanation... I suppose I need to default to the speakers somehow, but I can't find any documentation on how to do that in flutter, and I haven't yet learned how to override certain aspects of a flutter app with native swift/objective c code. If anyone has any suggestions, I'd love to hear them.
Attached are logs with and without the headphones plugged in to my iPhone.
With headphones:

Looks like the same logs to me, with no errors on either end. But it's like the sound is muted- and I've made sure that do not disturb mode is not on, silent mode is not on, I've checked button on the mute button on the side of the phone is not on... I have tried it on the emulator through Xcode and then the audio did play... But I can't figure out how to get it to work on my physical devices. Thanks for any advice!
I managed to solve it, with the help of this link AVAudioSession setCategory error
I added the following code to the AudioplayerPlugin.m file that is created in ios/Pods/.symlinks/plugins/audioplayer/ios/Classes
-(void) togglePlay: (NSString*) url isLocal: (int) isLocal
{
//ADDED START
NSError *error = nil;
BOOL success = [[AVAudioSession sharedInstance]
setCategory:AVAudioSessionCategoryPlayback
error:&error];
if (!success) {
NSLog(@"Error setting speaker");
// Handle error here, as appropriate
}
//ADDED END
NSLog(@"togglePlay %@",url );
if (![lastUrl isEqualToString:url]) {
[playerItem removeObserver:self
forKeyPath:@"player.currentItem.status"];
