Create new file /etc/event.d/userspace-fixes with content:

start on started hildon-desktop
service
console none
script
	if ! hal-device /org/freedesktop/Hal/devices/platform_soc_audio_logicaldev=
_input 2> /dev/null; then
		hal-device --add /org/freedesktop/Hal/devices/platform_soc_audio_logicald=
ev_input < /dev/null
		hal-set-property --udi /org/freedesktop/Hal/devices/platform_soc_audio_lo=
gicaldev_input --key input.jack.type --
strlist-pre "a"
		hal-set-property --udi /org/freedesktop/Hal/devices/platform_soc_audio_lo=
gicaldev_input --key input.jack.type --
strlist-rem "a"
	fi
