My Pulse Audio Volume Control (pavucontrol) is not shown volume bar which present below the volume control slider for right and left channels in the Play tab . However, I can hear audio,and the pavucontrol Play tab shows the name of the application(any media player vlc,mplayer etc.) which is running and volume control for right and left channels (FROM LEFT & FROM RIGHT Volume slider) . I am attaching screen shot when I am listening songs.
I guess there may be a change in the system configuration/setting? How to reset it?
I have reinstalled Pulseaudio, but the problem remains. I am using ubuntu 12.04 with default pulse audio.
