I don't have any problems as a normal user here.  Make sure the 
permissions on the directory you are in allows "write" for this 
user.

Using "alsamixer" I have a "Mic" volume control and a "Mic Boost" 
control.  The "Mic" control is a slider that I can vary between 0 
and 100, or mute with the "M" key.  The "Mic Boost" is just a 
on/off toggle using the "M" key.  With these I can control the 
volume from faint to loud.
