I cant hear the audio

I got the audio in sequence editor but there is none in the render (x vid) . I looked in the manual . I looked in tuts. they all say add audio and your done. I push the play button its there I here it (WAV) just not in the render.

Hello
you must select the “FFMpeg” render format and in the “Audio” tab, enable “Multiplex audio”!
Bye

Thank you very much.
