With the same half-plug, in OS X I head sound both via h/phones and internal speaker. Driver: snd-powermac. Audio card: Tumbler @ i2ca @ KeyLargo i2c (I can provide the full dump of OpenFirmware device tree). As at #alsa @ irc.freenode.net suggested, I ran `alsamixer -c 0` and MM-ed 'Auto Mute'. After that, I can fully plug h/phones jack and enjoy full sounds w/o distortions but still can't get any sound when it's unplugged.
