Question chassis speaker header connection

ASRock fm2a68m-dg3+ board, amd a6 7400k apu, evc3a 500b psu. I have no sound at all. Note: I don't know what to connect for the chassis speaker header.
Still a bit confusing:

review your boards manual:

page 16 at bottom, how to connect HD Audio connector from chassis to motherboard

page 18 at top how to connect the 'chassis speaker', which you have to provide if one didn't come with your case, and you can find one at sources in Calvin7's post.
