YouTube audio not playing

For about a week or so, whenever I visit YouTube and play a video I can’t hear the soundtrack. I’ve unplugged & powered off my speakers, tried headphones but still no good. A quick trawl of the net and all the fixes seemed to suggest dumping the contents of ~/Library/Preferences/Macromedia which did nothing other than stop Flash stuff from playing. But this little trick seemed to do the, um, trick.

Open up “Audio MIDI Setup” which is in your Utilities folder and set the Output Format (in the bottom right corner) to 44100.0Hz. You might need to change the source as well but that’s all I needed to do and now I can listen to Star Guitar in all it’s glory.
