I don't have any advice, but I have the same problem as you and describe it here:
I wonder if you are all having the same issues with QuickLook and QuickTime Player X when things start getting flaky. Rebooting always works. When it first happened, I tried to just log out, but that didn't help. Since then I've been rebooting once every day or three.
For what it's worth, I have a 2009 MBP.

I just updated my blog post because it looks like force-quitting the coreaudiod process in Activity Monitor fixes things without a reboot. Give it a shot and let me know if it works!

I have the same problem, found a post related to issues with the coreaudiod
1. Open Terminal
2. Type this "
3. enter your password
4. In textedit open /System/Library/LaunchDaemons/com.apple.audio.coreaudiod.plist
5. Change false to true
Will try this today.

Well, despite upgrading to 10.7.1 I still have this problem. It's annoying to have to go into Activity Monitor and quit coreaudiod any time I want to watch YouTube or VLC after being away from my computer for a short time.
I thought Macs were supposed to "just work."

I have about the same problem, even after upgrading to 10.7.1.
VLC and Quicktime have no audio and iTunes won't even play (stays at 0:00).
Erik's suggestion seems the only one that works without the need to reboot the system.
I have also found another discussion here where they are exactly talking about the issue we are currently experiencing.
"Same problem here. I found an easy way to fix it without rebooting.
Run terminal and do this:
sudo killall coreaudiod "
It's just another way round from Erik's suggestion.
However this is just an annoying temporary solution, I look forward to receiving soon an official fix from Apple.
Until now, it just does not work as it should...

Same problem here.
No Audio with Youtube (Safari & Chrome) and VLC. iTunes works.
Restarting helps though.
Computer is a mid 2011 iMac i5 running os x 10.7.1

Most videos on youtube are flash ( flv files ), and they are played not using QT nor any other app but instead courtesy of Adobes flash plugin while web-videos that use the HTML5 codecs ( webm files ) are played via QT plugin in safari or any other browser.
Might be flash-plugin related. It can have issues in 64bit mode which is in Lion the default for all apps.
Try changing temporarly Safari to run in 32bit mode ( and / or QuickTime Player too ) :
reveal the icon for the app in Finder, get-info on the app, select checkmark "run in 32bit compatibility mode" and restart the app(s) you changed ( you can always undo this ).
If safari runs in 32bits, all plugins auto-change to 32bit too ( they exist all in hybrid/fat/double versions in Lion = 32 and 64 , only rarely an app is 32bit alone ).

The issue isn't isolated to Flash at all. When audio starts causing problems (for reasons I can't figure out) it happens for non-Flash related video and audio as well. Today iTunes wouldn't play a video because of the issue. Killing coreaudiod either via Activity Monitor or Terminal (with 'sudo kill all coreaudiod') fixes things. My blog post, Weird OS 10.7 Lion Audio/Video Problems (and how to fix it), describes the problem and solution.
