Hi Mark,
I am very thankful for all code and help you provided. Since thursday I am able to play that data flawlessly. So please understand that when we talk about that issue it is not to help me, but to improve NAudio. Let's not talk about my files, sample rates or headers. I want to inform you that I hear stumbling if I use a block align which is not a divider of 2880 (1024 for example). You may use this information or not, it is your choice.
Bye
