Im receiving pcm audio data from a Stream which i want to playback in "realtime". Im not sure at all how to do this, except that i thought about switching between two buffers.

Are there any classes in .NET Framework 2.0 supporting audio playback using buffers ?

Any help (code examples) would be much appreciated .. as i am stuck with this problem (challenge) ...

thanks so far :)

I tried to use the SoundPlayer class for playback but encountered another problem here, which leaves me with a questions:

1. Is it possible to have a constant stream of audio which is played as it comes in, using the SoundPlayer class?. In my case i have one computer constantly sending audio PCM audio to another computer which needs to start playback of the audio the moment the first audio data arrives....

If not SoundPlayer is not the solution, so what is ? :)

I tried playing audio data received via bluetooth from another device sending a PCM Wave file binary using Yath Hyper-terminal. When received in my application im storing the audio data in a circular buffer. I made my own AudioStream class which implements Stream and overrides the methods. So when using the .Read(......) method im working on my audio data buffer instead.
The SoundPlayer instances is given the AudioStream instance (casted to Stream) but after calling .play() i get the error message "Corrupt audio header ...... something"

I would have postet some of my source code here, but since im not at work right now i dont have access to it. Will do tomorrow in hope of a solution.

Many Thanks in advance
