Is there any good GUI app to control my sound settings?
When I use Ubuntu, I use the sound indicator and have no problems with sound configuration. Unfortunately, sometimes sound stops working when I use an Ubuntu based distribution (for example, Lubuntu and Bodhi).
I searched in Google and read about Pulseaudio. Unfortunately, I did not manage to install it correctly. This is not an easy topic for me.
Thanks in advance

in the terminal if the GUI is broken. It's pretty easy to use; just use left/right key to move to different channels, and up/down key to adjust the levels. Then Esc to quit when you're done. – Paul Tanzini Dec 12 '13 at 15:30
