Hi all,

I'm trying to implement an option for users to play wave files in my MVC application, this is what I have so far

I get the data from the db, then I create a temp directory for my wave file and write the byte into the file

dt.Columns.Add("WavFile", typeof(string));
                    foreach (DataRow dr in dt.Rows)
                    {
                        try
                        {
                            if (dr["CallerAuthorization"] != null && dr["CallerAuthorization"].ToString() != "")
                            {
                                Byte[] tempAudio = (Byte[])dr["CallerAuthorization"];
                                if (tempAudio.Length > 0)
                                {
                                    dr["WavFile"] = CreateWavFile(tempAudio);
                                }
                                else
                                {
                                    dr["WavFile"] = "";
                                }
                            }
                            else
                            {
                                dr["WavFile"] = "";
                            }
 
                        }
                        catch (Exception e)
                        {
                            if (e.Source != null)
                                Console.WriteLine(e.Source);
                            throw;
                        }
                    }

public string CreateWavFile(Byte[] authorization)
       {
           string tempDir = Path.GetTempFileName();
           tempDir = tempDir.Substring(0, tempDir.Length - 4);
           tempDir = tempDir + ".wav";
           File.WriteAllBytes(tempDir, authorization);
 
           return tempDir;
       }

PartialView

<script>
    $(document).ready(function () {
        $(".audiobtn").click(function () {
 
                $.ajax({
                    type: "POST",
                    url: "/SearchPayment/PlayAuthorization",
                    data: { audio: $(this).find('img').attr('alt') },
                    cache: false,
                    success: function (response) {
                    },
                    error: function (error) {
                        alert("Unable to play audio");
                        console.log(error);
                    }
                 });
            })
        })
</script>

Controller

[HttpPost]
        public ActionResult PlayAuthorization(string audio)
        {
            if (audio != null && audio != "")
            {
                try
                {
                    using (SoundPlayer SPlayer = new SoundPlayer(audio))
                    {
                        SPlayer.PlaySync();
                    }
                }
                catch (Exception e)
                {
                    if (e.Source != null)
                        Console.WriteLine(e.Source);
                    throw;
                }
            }
 
            return new EmptyResult();
        }
    

After debugging the code it's giving me at error saying 'System.InvalidOperationException: 'Sounds API only supports playing PCM wave files.'

Does anyone know how I can fix this issue?

Thanks you
