Oh man I’ve spent so long not being able to watch Youtube videos, well they play but with no sound, bloody frustrating. Tried many lines of attack through Google and only just managed to crack it. The problem is widely reported but most of the suggested fixes don’t work.
- voodoo fix #1: the most widely “documented” fix is to launch /Applications/Utilities/Audio MIDI Setup.app and change the properties for built-in output from the default 44khz, to 96khz, then back to 44 – doesn’t work
- voodoo fix #2: this one I like, launch Garage Band and the audio prob will be fixed, nada
- the fix that works: delete the ~/Library/Preferences/Macromedia folder
Above prob occurs with latest software at the time of writing, btw:
- Safari 3.1.1
- Firefox, latest
- OS X 10.5.2
- Flash 9.0.124.0 – test your version
Update: this problem just happened to me again, using OS X 10.5.8 and Safari 4.0.3. Again, use the fix that works, restart Safari and problem fixed.

I have had this problem for a while. Nothing works not even this. I looked and didn’t even have a Macromedia folder in my preferences folder.
Any other suggestions? Any help is appreciated.

Wow. Thank you! I’ve looked all over the net for a solution. Deleting the Macromedia folder did it.
P.S.: If you don’t see a Macromedia folder in ~/Library/Preferences, look in ~/User/username/Library/Preferences. That’s where I found mine.
I had no idea how dependent I had become on YouTube until the audio vanished. It’s nice to be back in the age of “talkies” again.

Deleting the Macromedia folder worked – finally. Thanks!

Thank you so much! This one works. I have been concerned about this. The Macromedia folder didn’t want to go at first, but eventually I worked out that I had to empty the trash before the macromedia folder replaced itself, odd spawning behaviour. Well done and Thanks again.

The last one worked for me! Thanks!

Премного благодарен автору. Возможно, в будущем я и на самом деле реализую подобную затею.

Demian,
You were right – #3 worked.
Thanks SO MUCH – you ROCK!

THANK YOU! I had a slightly different problem where certain video sites wouldn’t work, but others would. I contacted Adobe, searched the web for help, posted on forums, but no one was able to help. Using your option 3 saved the day! I’ve had this problem for months; it’s nice to finally have it fixed!

thank you! i have been going crazy. just moved my studio around and everything has gone wrong. I’m waiting for my desk to explode…

How do you delete it? I just dragged it to the trash and it worked that way but didn’t
know if you had to get rid of it another way in order for it to reform. Thanks. Mine
cut off a few days ago and I didn’t have a clue how to solve it.
