This is what I did:
1) Open up a terminal and enter in the following:
2) Copy and paste the following into the file:
Save and exit.
2) Restart the sound server:
sudo /etc/init.d/alsa-utils restart
Now I can play sound in Amarok and Audacity at the same time. Not that I ever need to…but I’m tired of opening Audacity while Amarok closes and not being able to play any sound!
