... Then, you should have sound. Seriously, this is just weird - your chip is supported under ALSA since 1.0.16*. The only way your settings differ from mine is the HDMI Out. Then again, I think there were some occasions when I had to give it a sort of running start in order to get sound. Keep the volume control open, while playing some music or whatever with any media player, and see what happens on the different tabs when you connect and disconnect your headphone.
I... suppose you shouldn't see much going on, really, but keep in mind that you won't need anywhere near as much volume to get audible sounds from headphones as you would with normal speakers.
... AH, GOT IT! W-well, that is, I remember what I had to monkey around with to get sound. With the volume control/sound settings open, go to the Hardware tab and see if there's any change when you set the profile to Analog Output. If so, see if it changes back when you set it to Analog duplex again. Also check the Output tab - try the different connections.
* Or is it? It seems to be an ongoing story. I did a search at alsa-project.org, and there are entries in the change logs at least into 1.0.22 where work has been done for the ALC269
Ah, it seems Arch comes to the rescue yet again: https://bbs.archlinux.org/viewtopic.php ... 31#p888831
There was a suggested solution in the bottom post when I looked. Try it, and see what happens.
