Streaming raw bytes or chunks to MediaPlayer

[FallenDeity]

I have some audio data stored in my database as blob its about 2-3 mb instead of loading the whole data at once and passing it to the player to play as I am doing right now I would like to chunk the data into say sizes of 65536 bytes each and have the MediaPlayer play these arriving chunks. I have already managed to like load the whole blob at once and play it but when I start chunking it and pass the InMemoryRandomAccessStream while simultaneously writing to it nothing happens.

Chunking:

private async Task StreamTrack()
{
    if (_track is null) return;
    if (_trackStream is not null)
    {
        _trackStream.Dispose();
        _trackStream = null;
    }
    var conn = App.GetService<IDatabaseService>().GetOracleConnection();
    var trackId = _track.TrackId;
    var cmd = new OracleCommand("SELECT track_audio FROM tracks WHERE track_id = :trackId", conn);
    cmd.Parameters.Add(new OracleParameter("trackId", trackId));
    _trackStream = new InMemoryRandomAccessStream();
    var dataWriter = new DataWriter(_trackStream.GetOutputStreamAt(0));
    var reader = await cmd.ExecuteReaderAsync(CommandBehavior.SequentialAccess);
    if (reader.Read())
    {
        OracleBlob oracleBlob = reader.GetOracleBlob(reader.GetOrdinal("TRACK_AUDIO"));
        var bufferSize = 65536;
        var buffer = new byte[bufferSize];
        int read;
        while ((read = await oracleBlob.ReadAsync(buffer, 0, bufferSize)) > 0)
        {
            if (trackId != _track.TrackId) return;
            dataWriter.WriteBytes(buffer);
            await dataWriter.StoreAsync();
           _loaded = true;
            System.Diagnostics.Debug.WriteLine($"Read data {read}");
        }
        dataWriter.DetachStream();
        _track.TrackAudio = new byte[_trackStream.Size];
        var dataReader = new DataReader(_trackStream.GetInputStreamAt(0));
        await dataReader.LoadAsync((uint)_trackStream.Size);
        dataReader.ReadBytes(_track.TrackAudio);
    }
}

Playing:

public async Task PlayCurrentTrack()
{
    if (_track is null || !_track.TrackId.Equals(TrackId))
    {
        _loaded = false;
        await Task.Run(() => LoadTrack());
    }
    if (_track != null)
    {
        if (!_loaded) _ = Task.Run(() => StreamTrack());
        while (!_loaded) await Task.Delay(100);
        mediaPlayer.SetStreamSource(_trackStream);
        dispatcherQueue?.TryEnqueue(() =>
                   {
                       var page = (ShellPage)App.MainWindow.Content;
                       page.RhythmPlayer.PlayPauseIcon.Glyph = "\uE769";
                       mediaPlayer.PlaybackSession.Position = TimeSpan.FromSeconds(0);
                   });
        mediaPlayer.Play();
        progressTimer?.Start();
        IsPlaying = true;
        var current = _trackQueue.First?.Value;
        if (current is not null)
        {
            _history.Push(current);
            _trackQueue.RemoveFirst();
        }
    }
}

This approach is probably wrong I would be grateful if someone can point me in right direction regarding this.
