Hi Jolo and thanks for testing Oneiric!

Looking at the codec it seems like there is no volume control created for the headphones, so PulseAudio can't control it.

summary: - Headphones don't work
+ [Thinkpad R61] Headphones don't work due to "headphone" volume control
+ missing

It looks like this bug is the culprit for bug #911331 and maybe for bug #909348.

I wonder what happened with David Henningsson' patch.
In oneiric the headphones still did not work out of the box.

However I did find a workaround in
comment #19
options snd-hda-intel model=laptop-micsense
in /etc/modprobe/alsa-base.conf
also works for me.

This workaround worked for me: https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules

In some similar bug reports, other people solved their problem with this: https://help.ubuntu.com/community/HdaIntelSoundHowto

I have to say this was really painful for me: I had to search for a dozen hours before finally being able to use my headphones on a very common computer (Asus N73S).

How come this bug is still not resolved in Oneiric?
