I never received any feedback, but now I have more information. I also built and installed gnome-alsamixer, but it had an empty interface. I used strace with the mixers and saw it was trying to open some non-existing device files. Then I made the special device /dev/dsp/controlC. And the mixers now all worked. (So I thought.) And I could use aplay to play a wav file (to the headphone output only, not speaker output). Nevertheless, I could not make any changes. gnome-mixer, alsamixer and amixer would not make permanent changes. They didn't have errors, just next time you looked at the External Amplifier Power Down is still the same. > crw-rw---- 1 root audio 14, 3 Apr 9 20:19 /dev/dsp I removed that file.
