How to play an audio file in .NET MAUI

Mane, PRASHANT GORAKH 106

I want to play a sound on my mobile application (android and IOS)

So I've Added the sound file under the “Resource/Raw” folder with BuildAction=MauiAsset
and Added Nuget package "Plugin.Maui.Audio"

and used below code to play the sound

var audioPlayer = AudioManager.Current.CreatePlayer(await FileSystem.OpenAppPackageFileAsync("myaudio.mp3"));

 audioPlayer.Play();

but I'm getting FileNotFoundException exception.

Microsoft Q&A does not currently support third-party plug-in related issues. For MauiAssert, if you use this API without player, will there be an issue where the fileNotFoundException?

with the "Plugin.Maui.Audio" package try to use .wav audio format.

var audioPlayer = AudioManager.Current.CreatePlayer(await FileSystem.OpenAppPackageFileAsync("myaudio.wav")); audioPlayer.Play();

I'm unable to get MediaElement to work. The app keeps crashing with the error:

Java.Lang.AbstractMethodError Message=abstract method "void androidx.media3.common.Player$Listener.onSurfaceSizeChanged(int, int)"

There is no information anywhere that sheds any light on this error. I'm using Visual Studio 2022 v17.13.5, .Net 9 Maui.

My Code:

private static MediaElement MyMediaElement = new(); MyMediaElement.Source = "Resources/Raw/beep.wav"; MyMediaElement.Play();

The same thing happens to me, even applying the configuration mentioned in the Android implementation documentation.

Hello,

For playing media files, MAUI provides an official solution.

You could refer to MediaElement, and the following code sample:

After installing CommunityToolkit.Maui and CommunityToolkit.Maui.MediaElement, you could use the following code to play myaudio.mp3:

            builder
                .UseMauiApp<App>()
                .UseMauiCommunityToolkit()
               .UseMauiCommunityToolkitMediaElement()


<toolkit:MediaElement Source="embed://myaudio.mp3" ShouldAutoPlay="True"/>

Best Regards,

Alec Liu.

Hi @Yonglun Liu (Shanghai Wicresoft Co,.Ltd.)
Thank you for the reference code. but above code that you have given is for playing the audio from UI and it required user action and I'm looking a solution for playing .mp3 sound without User action,

The scenario is, I have list of items and each item has their own expiry time. I have played that sound before that item expired to just notify the user.

In fact, you can choose not to show the UI and manually control the playback of the audio in the background.

<toolkit:MediaElement x:Name="mediaplayer" Source="embed://myaudio.mp3" IsVisible="false" ShouldAutoPlay="False"/> mediaplayer.Play();

Hi @Yonglun Liu (Shanghai Wicresoft Co,.Ltd.)
it worked but only for single page where I have added that code. unable to play it when I'm on different page and I need to play that sound from service class. and also, I'm using background timer to trigger that service method.

Even I have added below code in service class.

MediaElement mediaElement = new MediaElement { Source = MediaSource.FromUri("url"), ShouldAutoPlay = false, IsVisible = false }; mediaElement.Play();

The MediaElement, as a view element, does need to be included in the page in order to play. If you need to play only in the background, it is better to post this feature request to GitHub to make our development team aware of it.

Mp3s stream fine on my IOS device but .WAV files do not. On Android devices I do not have a problem streaming WAV files. Is there a different approach for IOS?

Thanks for your feedback.

This is caused by the fact that iOS does not support the WAV format. You need to convert the WAV format to the format mentioned in the following document.

Audio Playback

Audio Playback

Supported formats include AAC, MP3, Apple Lossless, FLAC, Dolby Digital, Dolby Digital Plus, and Dolby Atmos

I have followed the same steps in the latest MAUI but the file is not loading and playing i have followed the below exception handing as well but no result what could be the issue.

<toolkit:MediaElement x:Name="onStartMusic" IsVisible="True"
Source="resource://onStart.mp3" ShouldAutoPlay="True" ShouldLoopPlayback="True"/>

method:
if(onStartMusic.CurrentState != CommunityToolkit.Maui.Core.Primitives.MediaElementState.Playing)

{

    onStartMusic.Source = MediaSource.FromResource("onStart.mp3");

    onStartMusic.Play();

    onStartMusic.MediaOpened += (sender, args) =>

    {

        Console.WriteLine("Audio file opened successfully");

    };

    onStartMusic.MediaFailed += (sender, args) => {

        Console.WriteLine($"Error playing audio:{args.ErrorMessage}");

    };

}

I have tried the following steps but still the music file is not playing with the resources/raw by using MediaSource.FromResource() method.

Please find the below code reference which i have tried and the permutation and combinations.

//onStartMusic.Source = MediaSource.FromUri("http://thinkingform.com/wp-content/uploads/2017/09/video-sample-mp4.mp4?_=1"); //this is working
                    //onStartMusic.Source = MediaSource.FromUri("https://samplelib.com/lib/preview/mp3/sample-12s.mp3"); //this is working
                    //onStartMusic.Source = MediaSource.FromResource("embed://onStart.mp3"); //made the music file as a embedded resource then also it did not worked.
                    //onStartMusic.Source = MediaSource.FromResource("Resource://Raw/onStart.mp3");
                    //onStartMusic.Source = MediaSource.FromResource("onStart.mp3"); //not loaded the music file
                    //onStartMusic.Source = MediaSource.FromResource("resource://onStart.mp3"); //not loaded the music file
                    //onStartMusic.Source = MediaSource.FromResource("resource://Resources/Raw/onStart.mp3"); //not loaded the music file
                    //onStartMusic.Source = MediaSource.FromResource("resource://Flora.Resources.Raw.onStart.mp3");
                    //onStartMusic.Source = MediaSource.FromResource("embed://Flora.Resources.Raw.onStart.mp3"); //not loaded the music file
                    //onStartMusic.Source = MediaSource.FromFile("E:\\Trainings\\MAUI\\Flora\\Flora\\Resources\\Raw\\onStart.mp3"); //this is working
                    //onStartMusic.Source = MediaSource.FromResource("Flora.Resources.Raw.onStart.mp3"); //not loaded the music file
                    //onStartMusic.Source = MediaSource.FromResource("//Flora.Resources.Raw.onStart.mp3");  //not loaded the music file
                    //onStartMusic.Source = MediaSource.FromResource("\\Flora.Resources.Raw.onStart.mp3"); //not loaded the music file
                    //onStartMusic.Source = MediaSource.FromResource("resource:\\Flora.Resources.Raw.onStart.mp3"); //not loaded the music file
                    //onStartMusic.Source = MediaSource.FromResource("Flora.Resources.Raw.onStart.mp3"); // After setting the file to embeded resource also not loaded the music file
                    onStartMusic.Source = MediaSource.FromResource("embed://Flora.Resources.Raw.onStart.mp3"); //not loaded the music file
