In many times my Ubuntu Karmic just stop its sound from being audible. I have very strong guess that this is because of Skype in my case. Before I found this link in ubuntuforum I had always restart my Ubuntu, which is very troublesome because I have to re-open all the things again. Based on information I found, I would like to share how to restart the sound without restarting your Ubuntu.These are how to do it:

1. run this command under your user : lsof | grep pcm
   it should gives you a list of application that holding the pcm, find its process id which is represented as numbers
2. stop the process id with the command : kill -9 <process id>
3. restart your alsa by typing this command : sudo /etc/init.d/alsa-utils restart

You should have your sound again.
