I was browsing YouTube last night and wanted to watch the clip of Steve Jobs’ interview on CNBC about the 5th Avenue Apple Store. When I got to the clip, the video was working fine, but I couldn’t hear anything. In fact, I couldn’t hear audio on ANY Flash 8 Video clip. I guess I had just not watched any since switching over to my new MacBookPro.
After searching the discussions at Apple Support, I finally had the solution. Go to Applications > Utilities > Audio Midi Setup. Look for the Properties For: drop-down and select Built-in Output. Here is a screenshot of the panel.
Now look under the Audio Output section and find the Format drop-down. Mine was set to 96000.0 Hz. Switching this to 44100.0 Hz returned audio to any Flash 8 video clip I watched.
I am not really sure why this was set to 96000.0, or why returning it to 44100.0 fixed it, but it did. I am also not sure if this happens on the new MacBooks either. I have a friend with a 15″ MacBookPro and his seemed to work fine. The only difference between mine and his is that he did not do the Migration Assistant to copy files from his Powerbook, and I did.
Check out the great Apple deals at Amazon.

Also, give this a try: open and close the Garage Band application. Suddenly, Flash Video’s audio works fine again.
Odds are that you had that setting on your old powerbook and it copies ALL the settings over.
Yeah, the audio from that file played just fine on my MBP out of the box.
Actually, it was a result of installing a copy of VLC player.
actually, unless your soundcard can output(decode) 96kHz frequency, you won’t be able to hear anything. In fact, most consumer soundcards can only decode up to 44kHz sounds. I had this issue before when the mp3 was encoded in 48kHz but I hear nothing, until I re-encoded it to 44kHz before it “worked”.. =)
