This sounds like a PAM problem.

Unfortunately, no.

I have had to fix such problems with sound by hand editing:


If this is the problem, this is the fix:

Make a group (if you don't already have one): "camera", give it a 3 
digit group number, and make all users that are allowed to use the 
camera a member of that group.  You can use: "KUser" to do this.

Edit this line of the file:

<console>  0600 <camera>     0600 root

Change it to:

<console>  0660 <camera>     0660

hope this works.
