Still, EPERM is a wrong error code in this situation. The information about kernel-image package and modules you gave me was very helpful. Now, what happens if you: - open another mixer, - change the microphone value (microphone input gain or something), - make sure it has changed by closing and opening the same mixer, - then close the mixer, - and run tkmixer under strace: will there be any difference in tkmixer's behaviour, particularly with respect to which ioctl causes EPERM?
