Getting Flash Sound to work under Google Chrome and Ubuntu 9.10

I’ve been increasingly frustrated by Google Chrome’s ability to play Flash minus sound. I don’t know what Flash plugin they are using but, luckily, the fix is easy. I just:
#>mkdir /opt/google/chrome/plugins
#>sudo cp /opt/Adobe\AIR/Versions/1.0/Resources/libflashplayer.so .

You’l notice I’m using the AIR version but my guess is you could use the one bundled with any other browser (e.g. Opera, Firefox). Just run:
locate libflashplayer.so
…and go from there.
