Yes it worked thank you very much

Thanks. Worked for me. Just quit everything, updated Flash (that did not fix it) and:

1. System Preferences > Other/ Flash Player > Advanced >  Delete  All

     Press the "Delete All" button.

Selected "Delete all site data and settings" (NOT selected Delete all audio and video license files) and then clicked Delete Data.

Great!

Mac OS X 10.8.5 - Safari 6.1.

just now that happened to me (no sound but video playing)

system preferences-flash player-advanced-browsing data and settings-delete all site and data settings and all audio and video files

and worked!

i didn't have to reopen safari

This also worked for me. First time. I had been having the no sound problem off and on for weeks. Thanks for the help.

Deleting the Flash site data worked!  I was also having the problem in the Spotify desktop app.  All is working well now, thanks!

It is now Dec 2014.  Does anyone know if the above solutions still work?  I'm afraid to find out before hearing your feedback.  Can anyone please help?  Thank you.

ApMaX - THANK YOU SO MUCH!!  This COMPLETELY worked for me!  Just tried it now - Dec. 31st, 2014.  I had been on other sites that had other instructions such as plugging headphones in and out or changing some other settings or even rebooting.  I'm so glad you posted this solution, because I had no idea that my problem was restricted to YouTube videos until I reflected that this was the only place that I could repeat the problem since I don't have anything else with sound downloaded.  And then I came across ApMaX's very simple solution and PROBLEM SOLVED!  Thank you again.  Please note I didn't try the other solutions listed in this post, so those may very well work also.  I just tried tried ApMaX's because it looked the most simple to me.  But Im thankful to all who took the time to post solutions for this issue.

thanks, regarding this:  all I see on my laptop is "Disable caches."  Is this the same as "empty caches"?

Empty Caches

Safari > Preference > Advanced

Checkmark the box for "Show Develop menu in menu bar".

Develop menu will appear in the Safari menu bar.

Click Develop and select "Empty Caches" from the dropdown.

thanks

This isn't working for me, I've deleted all in flash player but the other settings no longer exist in the safari drop down specifically "reset safari" what do I do now?
