Changing AudioFileReader.Position while paused caused garbled output

Mar 9, 2016 at 11:46 PM
I am doing MP3 playback using AudioFileReader and WaveOut.

I am able to set AudioFileReader.Position in code while a song is playing, and it works great. The playback jumps to the new position and continues without missing a beat.

However, if I call WaveOut.Pause(), then change AudioFileReader.Position, then call WaveOut.Resume(), the playback resumes, but the output is garbled. If I don't change the position in between the Pause() and Resume(), everything is fine. It's only the specific case of Pause() -> change Position -> Resume() that cause the garbled playback.

Is this a known bug, or am I doing something wrong?

Try to resume with "WaveOut.Play()" instead of "WaveOut.Resume()". I think this is might be an old WaveOut issue.

That worked, thanks! What is the difference between those two methods?

Looking at the source the difference is, that "WaveOut.Resume()" is calling the native restart function without enqueueing buffers like "WaveOut.Play()".
