CX20551 shows the connector option

Tried booting karmic live on Toshiba NB205, also using ALC272, but connector option does not show, please refer to the information below:
=====================
Simple mixer control 'Master',0
Simple mixer control 'Headphone',0
Simple mixer control 'PCM',0
Simple mixer control 'Mic',0
Simple mixer control 'IEC958',0
Simple mixer control 'IEC958 Default PCM',0
Simple mixer control 'Capture',0
Simple mixer control 'Beep',0
========================
Note: my another Dell engineering sample is also using ALC272, but connector option shows in that system.
