Sounds strange. MM-ing 'Auto Mute' would mean disabling it, so
plugging anything should have no effect.

You could try running alsamixer while plugging in the headphones. This
should be instantly visible: 'Headphone Detection' MM -> OO, 'PC
Speaker' OO -> MM. (when 'Auto Mute' OO)

On my iMac G4 800 MHz, with Tumbler audio and ALSA driver,
everything works with snd-powermac.
