Bug Description
I updated my Ubuntu Gutsy a few hours ago and sound suddenly stopped working.
I'm on a Thinkpad T61. Pressing the volume keys that are built into the laptop
display the popup volume meter but the bar is empty and refuses to move.
Running gnome-volume-
Gstreamer plugins and/or devices found." I'm new to Linux but it seems standard
from reading other bugs trying to solve this one to post this info:

Same for me on a Dell Inspiron Laptop after updated to kernel 2.6.22-12. Sound control doesn't work, same error message.
But I discovered it is not a gstreamer-bug!It is a bug of a wrong kernel, that was installed accidentaly after last update.
For me, I need the generic-kernel. After the last update, there were two kernels installed:
2.6.22-12-generic (the right one I need)
2.6.22-12-386 (which is the false one)
In the kernel list the -386 was the standard kernel, so Ubuntu started with the -386 kernel. And with that kernel sound isn't working, neither wlan!
If you start with the right kernel, that is 2.6.22-12-generic, everything is OK!
So the problem isn't gstreamer, it is the false -386 kernel! I will file a bug report for this.
