I was listening to some music with Amarok this morning when I wanted to watch the new The Happening trailer. To my annoyance there was no audio! After conducting a bit of googling, I learnt that it was because of Ubuntu using PulseAudio as its audio backend for Hardy. The fix is simple; install
sudo apt-get install libflashsupport
Then maybe log out and log back in .
It seems the reason
libflashsupport isn't installed by default is because of some problems some people are having with it.
