LOL, 2 days later I faced the problem...
I am ashamed to ask, but... what should I do instead?
When closing the form containing the above code I receive am error:
AcmStreamHEader dispose was not called at AcmStreamHeader.Finalize()
I tried to understand as many as I could, but it's really hard. The demo code does not work with VS2010 express (I don't have a vs2010 enterprise license) and, on the other hand, I can't find any specific documentation talking about a simple task (in my eyes) as playing some audio should be.
Any kind of help will be a lot appreciated.
Thanks in advance
