Jwplayer mute doesn't work with HLS stream -

i'm trying implement mute button on hls stream in jwplayer. found example on official site. i've copied code:

<div id="myelement"></div>  <script>     jwplayer("myelement").setup({       file: "/uploads/myvideo.mp4",       width: 640,       height: 270,       autostart: true,       mute: true     }); </script> 

and replaced file property on

http://android-hd.izletv.mobi:80/org5/trt1_me/chunks.m3u8 

and on ipad still can listen sound. what's problem?
