Can you provide us with a sample of the code that you are using. An explanation of what the issue is and when you are experiencing it?

[ALSULTAN]

using Plugin.Maui.Audio;

namespace ALSULTAN.Media
{
    class Audio
    {
        static IAudioPlayer KitchenBeepPlayer;
        static Stream KitchenBeepFile;
        internal static async Task PlayKitchenBeep()
        {
            if (KitchenBeepPlayer?.IsPlaying == true) return;
            KitchenBeepFile ??= await FileSystem.OpenAppPackageFileAsync("Audio/message_nudge.mp3");
            KitchenBeepPlayer ??= AudioManager.Current.CreatePlayer(KitchenBeepFile);
            KitchenBeepPlayer.Stop(); // Exception here....
            KitchenBeepPlayer.Play();
        }
    }
}

It sounds like the stream your file is in doesn't support seeking. You can check this by calling .CanSeek on your stream and see what it returns.

I think we should be guarding against this anyway though.

[ALSULTAN]

Actually .CanSeek returns true. and your library works fine with this file but sometimes the error occures.

On Android (Same Code Above):

Plugin.Maui.Audio.FailedToLoadAudioException: Unable to create AVAudioPlayer from data.
   at Plugin.Maui.Audio.AudioPlayer..ctor(Stream audioStream, AudioPlayerOptions audioPlayerOptions)
   at Plugin.Maui.Audio.AudioManager.CreatePlayer(Stream audioStream, AudioPlayerOptions options)
   at ALSULTAN.Media.Audio.PlayKitchenBeep()

Out of interest why are you calling Stop before Play?

[ALSULTAN]

Out of interest why are you calling Stop before Play?

Because the audio maybe playing when the method is called, so stop the playback and start new one

The if statement on the first line of your method means that won't happen. If you remove the Stop call does it still through an exception?
