My sound isnt working on youtube but it is on itunes! Why?

So from your question it definately seems that everything is fine with your speakers/headphones. It may be a glitch on youtube. Have you checked if the sound on the videos is turned on. I hope I helped.

Like everyone else here, I say check your sound on YouTube as well as your soundsettings on your computer. This happened to me once, and later when I rebooted my computer the sound was back.

I see questions similar to yours every few days on Y!A now, so I recently did a whole lot of Googling, searching, reading and poring over dozens of discussion threads and websites, only to realize that there are no definitive answers out there. The only semblance of a part solution which kind of worked for a few people would require you to either: 1 -- fool around with your "registry" (which I would be totally deadset against because that could really screw things up); 2 -- download some utilities (which I would be just as much against, because that kind of stuff is what probably created your problem in the first place). Thus, my first piece of advice is to shutdown then reboot. If that doesn't work, clear your "cache" of "Cookies", "History" and "Temporary Internet Files", thus making your computer "fresh" in YouTube's eyes. My infamous "CHTIF" triple-cure has resolved hundreds of YouTubers' problems. So why not yours. Please reboot after doing this: Internet Explorer 6: → Tools → Internet Options → Delete Cookies → OK → Delete Files → OK → Clear History → Yes → OK Internet Explorer 7: → Tools → Internet Options → Delete... → Delete files → Yes → Delete cookies → OK → Delete history → OK → Close (browsing history window) → OK Mozilla Firefox → Tools → Clear Private Data [x] Browsing History [x] Download History [x] Saved Form and Search History [x] Cache [x] Cookies → Clear Private Data Now Apple Safari 3: → Edit → Preferences → Security (tab) → Show Cookies → Remove All → Done after that: → Safari → Empty Cache → Empty after that: → History → Clear History If that does not do the trick, here's some other suggestions: ♦ If you've got GWA or any kind of "accelerators", get rid of them immediately because they make YouTube do strange things. Also, running applications (like AIM, AOL, ICQ, and Yahoo "Messenger") can interfere with YouTube. ♦ There could also be conflicts with other video players that are installed on your computer, like Windows Media Player, Real Player and QuickTime. Check all of their volumes, too. ♦ The newer versions of Flash are frustrating a whole bunch of YouTubers. Most updates are typically good for only one thing: software conflicts. If you are using 1 of the 8 versions of Flash 10 (yes, there actually are 8), you should consider the Asker's comments on this other "Best Answer" of mine: http://answers.yahoo.com/question/index?qid=20081125075929AABZpVS ♦ Who knows why, but sometimes YouTube works better if you tinker with the URL from "www.youtube.com" to simply "youtube.com" (or you could even try "ca.youtube.com"). ♦ Some people found success by just closing their browser and restarting it. A couple others rebooted, and one person wrote to me recently saying that everything started working magically again the next day with no effort on his part; thus your problem might just be a temporary glitch. If you're able to determine the "cause" and its "cure", could you please click on my avatar and write to me so that I can include it in my future Yahoo! Answers. One other apparent cause so far seems to be if you download "Torrents" music. I wish you luck and hope that there's something in my long answer does the trick for you. Here are 2 other possible solutions to videos with no sound. They might seem old but they both got very positive results: FIREFOX + VISTA zarin denatrose . wordpress . com / 2008 / 07 / 31 / fixing - sound - firefox - vista / http://zarindenatrose.wordpress.com/2008/07/31/fixing-sound-firefox-vista/ WAVEMAPPER www . my digital life . info / 2007 / 08 / 15 /adobe-flash-no-sound-wavemapper-trick/ http://www.mydigitallife.info/2007/08/15/adobe-flash-no-sound-wavemapper-trick/

check the volume setting of ur computer from control pannel.then play agin

check the volume bar on the youtube video or reinstall flash player or if you're using vista click the volume icon and make sure your browsers volume isn't down

go to youtube. Click on the video you want to watch. Down the bottom right of the video will be the volume. hover your mouse over the volume icon and drag the little bar to the top. If it is not as simple as this then make sure you have the latest flashplayer and updates

I would check your volume settings because on my computer ( I have Vista) you can select certain websites to be muted or to have lower volume. If that's the problem all you have to do is slide the bar up so you can hear it or click unmute. Hope this helps :)
