No Audio in online flash videos [garageband didnt work]

quicktime works online [so do system alerts, itunes, etc] but youtube/myspace/google videos, pandora radio, project playlist all have no sound in web browsers (safari, firefox). this is happening on all user accounts on the computer.
it seems to be a common problem but none of the following has worked for me:
• ive tried opening garageband and adjusting audio midi [doesnt even go up to 96kHz only 48]
• reinstalled flip4mac
• reset PRAM
• ive emptied safari cache, trashed macromedia prefs
• checked the MIME quicktime panel settings
• all four of the safari web content boxes are checked
• ran disk utility: verify/repair disk permissions
safari: 3.0.4, quicktime: 7.3, wmv player:, foxfire:, adobe fp:
help? i love my mac but all these silent videos arent really my thing.


Hi Dramamine and welcome to the forums!
Sounds like a Flash problem.
These are the downloads and the settings you need in order to view/hear pretty much everything that the net can throw at you: The setup described below has proved repeatedly successful on both PPC and Intel macs, but nothing in life carries a guarantee!
It is known to work in the great majority of cases with Safari 3.0.4, QT 7.3 and OS 10.4.11. (If you are running Leopard, ensure that all plug-ins have been updated for OS 10.5)
Assuming you already run Tiger versions OS 10.4.9 or above (this has not yet been verified with Leopard) and have Quicktime 7.2 or above, and are using Safari 2 or 3, download and install (or re-install even if you already had them) the latest versions, suitable for your flavor of Mac, of:
RealPlayer 10 for Mac from RealPlayer%2010&proc=g3&lang=&show_list=0&src=macjack
Flip4Mac WMV Player from (Windows Media Player for the Mac is no longer supported, even by Microsoft)
Perian from
Adobe FlashPlayer from
(You can check here: to see which version you should install for your Mac and OS. This: may also interest you.)
In Quicktime Preferences, under advanced, UNcheck Enable Flash, and under Mime settings/Miscellananeous only check Quicktime HTML (QHTM).
See also the very informative post from QuickTimeKirk dated Dec 3, 2007 in this thread:
In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them).
Now go to Safari Preferences/Security, and tick the boxes under Web Content (all 4 of them).
Lastly open Audio Midi Setup (which you will find in the Utilities Folder of your Applications Folder) and click on Audio Devices. Make sure that both Audio Input and Audio Output, under Format, are set to 44100 Hz.
Important: Now repair permissions and restart.
The world should now be your oyster!
You should also consider having the free VLC Player from in your armory, as this plays almost anything that DVD Player might not.
