I have a problem with my internet-sound, whenever i play any sound in the internet explorer(or firefox, or opera) i cant hear anything.. For example, when i try to view anything on youtube, i can see the video, but i cant hear any sound...same with trying to watch some television live online... its the same on my myspace, and on everything else..... However, when i download something from the internet, it works perfectly well... In my internet explorer, in "tools"-"internet options"-"advanced"-"multimedia"-"play sound on webpages" is checked.... so i dont really know what to do.. CAN ANYONE HELP ME????
