I'm not going to be of any help here, I have such a negative reaction to noisy applications (other than games) that I rarely even look for an option to silence them, I simply kill the page or uninstall the app! Please, please give the user the option to silence your app unless it is an integral part of your solution (a sound on a tab does not seem to qualify for integral!).
Never underestimate the power of human stupidity
I solved it so, that I have small SeccondaryBuffer (size is much smaller than size of replaying WAV) and SeccondaryBuffer is in loop. Paralel Timer writes new data in to small SeccondaryBuffer from large byte array of WAV.
I created a new WinForms project and got this error:
The designer could not be shown for this file because none of the classes within it can be designed.
I have not yet added any code to the project. It appears as if all of the necessary assemblies are referenced, but intellisense can't seem to resolve the Form class.
Shutting VS2012 down and starting it back up again solved the issue. Weird.

Maybe the fact that I mentioned WPF when the OP was looking for ASP.NET was the reason. I don't see how my answer was wrong in that context as you could esily substitute the WPF front end with a ASP.NET version (or have both, and....).
