(Facepunch.Steamworks) Voice is not working

Hi,
I am trying to get my voice in "realtime" with the Facepunch.Steamworks library -> for later use as an VOIP game client.
But instead of hearing myself, I am getting strange beep noises only...
I really can´t figure out, what i am missing to hear my voice.

Here is the code i am working on right now:

Code (CSharp):

1.  
2.     void Update()
3.     {
4.         VoiceChat();
5.     }
6.  
7.     void VoiceChat()
8.     {
9.         var stream = new System.IO.MemoryStream();
10.         var output= new System.IO.MemoryStream();
11.  
12.         SteamUser.VoiceRecord = Input.GetKeyDown(KeyCode.K);
13.  
14.         if (SteamUser.HasVoiceData)
15.         {
16.             int length = SteamUser.ReadVoiceData(stream);
17.             SteamUser.DecompressVoice(stream, length, output);
18.  
19.             AudioClip audioClip = AudioClip.Create("WAV", length, 1, 22050, false);
20.             float[] floatArray = new float[length / 2];
21.             print(floatArray.Length);
22.             for (int i = 0; i < floatArray.Length; i++)
23.             {
24.                 try
25.                 {
26.                     floatArray[i] = (short)(stream.GetBuffer()[i * 2] | stream.GetBuffer()[i * 2 + 1] << 8) / 32768.0f;
27.                 }
28.                 catch
29.                 {
30.                     break;
31.                 }
32.             }
33.             audioClip.SetData(floatArray, 0);
34.             GetComponent<AudioSource>().clip = audioClip;
35.             GetComponent<AudioSource>().Play();
36.         }
37.     }

I am using the newest 2.0.a1 release.

I also unsuccessfully tried "output" instead of "stream".
I think SteamUser.DecompressVoice is not doing anything at all.

Could someone please help me out, fixing this issue.
Thanks in advance!
