I upgraded from ubuntu 10.04 to xubuntu 12.04. The speakers of my laptop are not working and I have a usb speakers to hear the audio. When I had 10.4 I opened sound setting and selected the usb speakers on the output device and were able to control the audio with the function keys and mouse buttons. After the upgrade to xubuntu, I installed the pulse audio volume control to access the sound settings and select the output device, but I cannot control the volume of the speakers unless I use the pulse audio volume control to change the volume. When I use the function keys and the mouse buttons it control the volume of the headphones but it does not control the usb speakers.

Anyone knows if that issue can be solve? I'll like to control the volume of the usb speakers with the same keys as the headphones.
