No Sound With Flash
Dude, this issue has been bugging me for months on my Mac... A couple apps would never play any sound (most notably Macromedia Flash). Anyway, I finally was able to find the solution, so hopefully someone searching Google will find this post useful.
Go to Applications -> Utilities -> Apple MIDI Setup
Check the Audio Output Format (somehow mine was set to 96000.0 Hz) and set it to 48000.0 Hz (or lower).

So to celebrate that I have Flash audio again, I'm glad to present you with a newly released Denny "Blazen" Hazen video (the funny thing about this video is it's actually 100x better than his previous ones)...
I'm a boy... from San Diego, CA (USA). And I don't really have a whole lot else to say about myself.
