That's an ALSA driver bug. Unfortunately I don't know how to fix AC'97s.

There does not seem to be any kcontrols indicating that you have speakers,
therefore no "Analog Speakers" port. 

It seems to me that if "Master" controls the speaker but not the headphones,
"Master" should be renamed to "Speaker".
