Is MediaPlayer audio playback supported in winUI 3 desktop apps?

[brabebhin]

Hello,

I have begun experimenting with migrating my media player from UWP to WinUI 3 desktop app, and I found the following that audio playback does not seem to work. I got video playback going fine with frame server mode, but there is no audio in sight.

Any thoughts?

var firstVideoFile = (await KnownFolders.VideosLibrary.GetFilesAsync()).LastOrDefault(); if (firstVideoFile != null) { player.AutoPlay = false; player.AudioDevice = (await Windows.Devices.Enumeration.DeviceInformation.FindAllAsync(Windows.Devices.Enumeration.DeviceClass.AudioRender)).FirstOrDefault(); player.AudioCategory = MediaPlayerAudioCategory.Movie; player.MediaEnded += Player_MediaEnded; player.MediaFailed += Player_MediaFailed; player.MediaOpened += Player_MediaOpened; playerElement.SetMediaPlayer(player); MediaSource source = MediaSource.CreateFromStorageFile(firstVideoFile); source.OpenOperationCompleted += Source_OpenOperationCompleted; player.Source = source; player.IsMuted = false; player.SystemMediaTransportControls.IsEnabled = true; player.SystemMediaTransportControls.IsPlayEnabled = true; player.SystemMediaTransportControls.IsPauseEnabled = true; }

Never-mind, it is just me getting rusty and not checking the codecs...

Are there docs for this? Not finding much with a quick Google search beyond this...
