I read a file and can play it

Me._StreamData = Application.GetResourceStream(New Uri("Sound/" & _WaveFile, UriKind.Relative)).Stream
                    Dim Wav As SoundEffect = SoundEffect.FromStream(strmAudio)

Now I've tried to modify the data. But I am not successfully. If I read the same file by using a IO.MemoryStream (I see there are the data included), the API fails on

Dim Wav As SoundEffect = SoundEffect.FromStream(strmAudio)

With error on strmAudio.

InvalidOperationException

As far as I see, the IO.Memorystream cannot be played, even if it has the Wave header included or not. Can you confirm or have I bad Wave header?

Does it work if you use `strmAudio.Position = 0;` just before the `FromStream` method? – keyboardP Jan 18 '12 at 01:48

For dynamic sound generation you can also use `DynamicSoundEffectInstance` to play sound from raw buffer – Ku6opr Jan 18 '12 at 08:08
To Seek to 0 or set Position to 0 is a good idea. I already do this explicit. While reading out the position it goes to 0 correctly. But it has this error any way. – Nasenbaer Jan 18 '12 at 10:19
thanks Ku6opr for your advice – Nasenbaer Jan 18 '12 at 10:34
Ku6opr, if you write your short text in the answerbox, I will accept it as solution. – Nasenbaer Jan 19 '12 at 10:51
