I guess I have only one device so there is nothing to set.

How is recording enabled? Do I need to add myself to some group? I am
member of followin groups: pankaj cdrom floppy sudo audio dip video
plugdev netdev bluetooth scanner.

I have tried to set input volume using various knobs in gnome settings
as well as alsamixer. It did not work.
