Audio currentl y does not work on a Thinkpad X230 (not the tablet!) via docking station. I've installed the mainline kernel from http://

@darthvader, I don't know, but I think it should be. Please file a separate bug with this command "ubuntu-bug audio" as your machine is different from this bug's machine. Thanks!

@darthvader - That model needs a separate patch, which has just landed upstream in the 3.6 kernel and should be available in 3.6-rc2:

ALSA: hda - add dock support for Thinkpad X230
As with the ThinkPad Models X230 Tablet and T530 the X230 needs a qurik to
correctly set up the pins for the dock port.

This bug is awaiting verification that the kernel for Precise in -proposed solves the problem (3.2.0-30.47). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-

Since the commit for this issue came in via a stable upstream release, I'm tagging it as verified.

I just installed the latest linux release on precise-proposed, and it did not fix the problem. The version it installed is 3.2.0.30.32, not 47, so I'm not sure if the newer release actually fixes the problem. However, I don't know how to actually install 3.2.0.30.47.
The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.

Confirming that 3.2.0-31.50 produces sound from an Ultrabase Series 3 with a X230 (not tablet), correctly handling pluggin in/out of both the Ultrabase and the Thinkpad. (mine isn't a tablet, but 3.2.0-30.32 didn't work with respect to audio from the dock)
However there is a very strange effect: when plugged into the Ultrabase, every time I do a "GUI highlight" (select an indicator, hover over a menu item, switch windows), there is a cracking static-like noise from the headphones. This is independent of the mouse used, and selecting an indicator and browsing left/right with the keyboard has the same effect, just like alt+tabbing. Simply writing as I do now also causes a very weak static noise, but it's barely audible.
The explanation of "dodgy wiring" within the Ultrabase AFAICT makes little sense because of how the error occurs. I've tried every sensible port combination of USB mouse+keyboard and audio jack on Thinkpad and dock: it consistently produces noise when the headphones are plugged into the dock.
Using the audio jack on the Thinkpad itself causes no such noises, i.e. it's absolutely quiet and the music is perfectly clear.
Should I file a separate bug for the non-tablet X230? And do we get an ETA on when the X230 specific fix by Felix Kaechele is going to land in the LTS release?

I'm having this same problem on my Lenovo T430 and Ultrabase Series 3.
No audio from the dock jack.
I've also commented on bug 893611 since that's also related but I'm a little confused whether I should be commenting on all of these bugs that I find that don't use the exact same model of laptop as I do or whether I should create a new bug for my exact configuration.
