Commented Issue: Buffer not dispose [16391]

I'm Trying NAudio in my project.
It seem that in Mp3FileReader buffer dispose function not work.
I use this scenario:
mp3_1 = New Mp3FileReader("FileAudio.MP3")
DSO1.Init(mp3_1)
DSO1.Play()
Then stop and dispose WaweOut and restart a new file with same routine.
After any stop and play, memory is loss.

Is this routine correct?
