Nobody to help ? Could someone confirme that you don't need to plug the headphones to get the subwoofer working ? Here is what I have in syslog concerning the hda-intel :

When I do so, the sound starts to play in stereo. I would love the sound output to be stereo by default and not be forced to plug anything to achieve that. Attached is the alsa-info.sh output for my machine.
