If you're using Chrome from the dev or unstable channels, you
probably have a bad Flash plugin enabled (this affects HTML5
audio as well for some obscure reason).  To fix it, go to
chrome://plugins and disable all the flash plugins. Then click
+Details to show the individual versions of Flash, enable them
one at a time until the problem goes away.  This is the
configuration that worked for me:  flash plugin configuration in
chrome  If you none of the versions you have work, you may need
to install the adobe-flashplugin package:  sudo apt-get install
adobe-flashplugin share|improve this answer Sadly if you only
have the NPAPI version enabled most websites seem to think you
don't have flash at all! –  Timmmm Jul 24 '12 at 21:05 Yes,
