It doesn't have the errors once I manually created the devices.
It works through the headphones port only.

Alsamixer v.1.0.4 shows:
Card: Intel 82801BA-ICH2
Chip: Analog Devices AD1881A
Item: Master
(By the way, alsamixer looks nice when displayed remotely via rxvt and
looks strange on the local system with xterm.)
Now I see I can change the Playback on and off for External Amplifier
Power Down, but it doesn't ever change the 0 to 1.

Maybe my speakers outputs are broken. I may take this system a part. I
have two identical systems to test too. At least the headphones output
works, but is too quiet.
Thank you, Clemens, for helping. If you need more information, please let
me know.
