New Post: WaveOutEvent buffers is null

Every once in a while when I close my application while using WaveOutEvent i get a NullReferenceException from the DoPlayback() function.  It turns out this.buffers is null.

Screenshot from VS2010, when Exception happens

A bandaid to fix the problem I now check for the null value in DoPlayback();

private void DoPlayback()
{
            if (this.buffers == null || this.waveStream == null)
                return;

            TimeSpan waitTime = TimeSpan.FromSeconds((double)this.buffers[0].BufferSize / (this.waveStream.WaveFormat.AverageBytesPerSecond * 2));

.........

}

I dont get a good stack trace back for some reason, I assume the call to DoPlayback()  is still in the ThreadPool  after I dispose of WaveOutEvent?

ThreadPool.QueueUserWorkItem((state) => PlaybackThread(), null);

Maybe the cure (not bandaid) would be to "un-queue" the thread form the pool on disposal?  not sure if that is possible or makes any sense...

I hope this helps, or maybe I am just doing something wrong...
