thanks to unys who ask me about this..following my view that knowledge is meant to be shared,i will post it here...
actually i figure out how to do it by trial and error..bakadasu did tell me about his way of putting the audio..but it didn't work for bolt.com..so i kinda tweak the code here and there..not so much of a tweak maybe becouse its so simple...hehe
1.go to the bolt.com page of any audio or video
2.copy the embeded link it provide..it will be something like this
<embed src='http://www.bolt.com/video/flv_player_branded.swf?contentId=1793374&contentType=2 loop='false' quality='high' bgcolor='white' width='365' height='340' name='video_play_500' allowScriptAccess='sameDomain' type='application/x-shockwave-flash' pluginspage='http://www.macromedia.com/go/getflashplayer39; /><br/>Upload videos at <a style='font-family:arial,sans-serif;font-size:12px;color:#0066CC' href='http://www.bolt.com39;>Bolt</a>.
4.not yet..from the edited code..just add " '/>" to its tail..
5.now the code is ready to be paste in the tag field of you profile setting..and then update..
(go setting-->profile)
