I installed Feisty when it was just a beta. Now it is stable and I ran apt-get update, upgrade, dist-upgrade. I am having troubles with the sound. When clicking on the GStreamer volume control on the desktop it outputs an error message:
No volume control GStreamer plugins and/or devices found.
I have no clue how to deal with sound. It would be very great if you could give me some tipps where to start fixing this problem at least.
