ThinkPad Mini Dock Series 3 problem with Audio output

Bug Description

I'm having a rather strange problem with the audio jack on the docking station. Using the headphone jack the external speakers work fine. When no speakers are plugged in the integrated speakers work. But when I plug in the speakers into the docking jack the integrated speakers get muted, but no sound comes from the external speakers.

WORKAROUND: Add the line:
options snd-hda-intel model=thinkpad

to the end of:

then reboot.

Do you know if this issue happened in previous version of Ubuntu, or is this a new issue?

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to . If possible, please test the latest v3.2-rcN kernel (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the others). 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 by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.2-rc1 fixed and issue, the tag would be: 'kernel-fixed-upstream-v3.2-rc1'.

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'. If you believe this bug does not require upstream testing, please add the tag: 'kernel-upstream-testing-not-needed'.

Thanks in advance.

I have not tested this setup with another version of Ubuntu, so I don't know if it's a new bug.

This being natty I was also unable to test the 3.2 release candidates (I tried anyway but got into trouble for doing so...) so I have to flag this one as kernel-unable-to-test-upstream.

Will upgrade to oneiric to see if problem persists.

Upgraded to oneiric, problem persists with new 3.2-rc2 kernel.

Had to downgrade again, so we're back to the status of the original bug post.

Same problem here (Thinkpad T420s; Oneiric; MiniDock 3). I can hear laptop-related buzz through the miniport jack, but no actual audio. Headphone jack on the laptop works fine.

Had same problem on Thinkpad W520, Oneiric 64-bit, MiniDock 3 and found this post:

Adding the line 'options snd-hda-intel model=thinkpad' to the end of /etc/modprobe.d/alsa-base.conf then rebooting seemed to fix the problem for me.

cdecker (cdecker) wrote :

Worked like a charm. Is there a way to include thinkpad detection during installation and add the line if a thinkpad is detected? Would solve it for all future installs :-)

Thanks for pointing us to the workaround with 'options snd-hda-intel model=thinkpad'. Works perfectly for me too.

Same symptoms here, not sure if I should open a new report because I'm using a different dock.

OS: Ubuntu 12.04 amd64, 3.2.0-20
Hardware: Thinkpad X230 and Ultrabase Series 3

Plugging the headphone into the Thinkpad itself works, pulling it out has music coming from the Thinkpad's speakers, but plugging it into the Ultrabase correctly mutes the Thinkpad yet leads to no output (very slight static noises).

Adding the model=thinkpad line and rebooting doesn't change the situation. alsamixer offers two devices: HDA Intel PCH and ThinPad Console Audio Control. Changes on the former correspond to real audio changes, but the Console Audio Control only has one muted unchangeable "Console" mixer.

Mistyped my kernel version there, it should be -30 of course.

Here's the report dealing with my particular problem:
So I guess my bug is unrelated here.

I'm having this same problem on my Lenovo T430 and Ultrabase Series 3.

OS: Kubuntu 12.10 beta 1 (also tested on 12.04 and it behaves the same).

The workaround mentioned above (adding the model=thinkpad line to alsa-base.conf) does _not_ work in this case.

Should there be a new bug or is this related enough to this one to keep it going?

@Stefan - and others,

This is something that needs to be fixed once per type of laptop, so this is essentially one bug per machine. Essentially, for every laptop, we need to add its ID to a table to support the docking station.

Looking at the upstream code, below are the machines currently supported, with ID number and well known name. If you have one of these, and it does not currently work, you can probably make it work by following this procedure:

If it is not listed, please file a new bug (using the "ubuntu-bug alsa-driver" command, as this will automatically attach the relevant ID), then write a comment in this bug with a pointer to the new one. Thanks.

Ok thanks.

Just one question. There are no packages for Quantal (12.10) on that download page that the wiki page points to. Any idea when to expect one or whether I should request that one be created (and if so, where do I do that then)?

Kind regards and thanks for your great work!
Stefan Freyr.
