Bug Description

I have a Lenovo ThinkPad T430 and an UltraBase Series 3 docking station.

If I plug my headphones into the jack on the computer, everything works fine. The computer speakers mute and the audio is played in the headphones. However, if I plug into the docking station headphone jack the computer speakers are muted but there is no audio in the headphones.

I've found two other bugs that are similar, bug 893611 and bug 1026953, but they specify a different type of computer/tablet so I decided to file a new bug.

Also, the workaround mentioned in bug 893611, adding "options snd-hda-intel model=thinkpad" to alsa-base.conf does not work for me.

Would it be possible for you to test the latest upstream kernel? Refer to . Please test the latest v3.6 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. Please only remove that one tag and leave the other tags. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Hi. Just checking up on this... it's my understanding that this is just a matter of adding the model name to a source file really and from what I can see this hasn't been done:;a=blob;f=sound/pci/hda/patch_realtek.c;h=bb93f927f7be97ac7280c87fe2cccbf448c73809;hb=4407be6ba217514b1bc01488f8b56467d309e416

There is a line for T430s there but none for T430.

But this brings me to a (potentially very stupid) question. Why in the world are these "quirktables" kept in a source file that needs rebuilding for each new model that comes along? Wouldn't it be a better idea to keep these in a config file that people can edit? This should simplify testing, instead of having to rebuild a kernel, you can just edit a config file and report if that worked. Am I missing something here?

Ok I guess it's better to send this in as a file and mark it as a patch. So here it is.

Joseph Salisbury (jsalisbury) wrote :


I created a Quantal test kernel with a Quirk for the T430. The test kernel is available from:

Ensure you install both the linux-image and linux-image-extra .deb packages.

Can you test this kernel and report back if it resolves this bug? If it does, I can submit a SRU request to the kernel team mailing list.

So just out of curiosity, what versions of the kernel will this go into? 3.5? or only 3.6/3.7? Will this be an Ubuntu patch for the 3.5 kernel? I'm basically just trying to ask whether I'll see this in the official kernel for 12.10 at some point?

Joseph Salisbury (jsalisbury) wrote :


This fix will be included in the official 12.10 kernel. I also sent your patch upstream, and will be applied against the mainline 3.7 kernel. Thanks again for all your help.

I seem to have same issue sounds works fine till I put laptop in docking station

@Mark, the patch was included in the upstream kernel 3.2.33. It should eventually arrives in 12.04.

Stefan Freyr (stefan-freyr) wrote :


I just updated my kernel to 3.5.0-18 but the patch does not seem to be present in it. Did it not make it into that kernel build? When can we expect it to be in the official 12.10 kernel?

This bug is awaiting verification that the kernel in -proposed (3.5.0-19.30) solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-quantal' to 'verification-done-quantal'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See for documentation how to enable and use -proposed. Thank you!
