I have the some problem, on my Thinkpad R61i, with natty everything work fine, but with oneiric the headphone makes no sound at all..

(I even tried to use "options snd-hda-intel model=thinkpad" in alsa-base.conf but nothing changed)

Fili (rogerwilco) wrote :

I also had no output on the headphones of my Lenovo Thinkpad R61i, adding

options snd-hda-intel model=generic

to /etc/modprobe.d/alsa-base.conf helped.

with model=generic it works perfectly, thank you!

Jochen Schnelle (noisefloor) wrote :

The additional line works fine, thanks!
In addition to that, general volume is addjustable in a wider range and more "fine-grained".

The additional line with "generic" worked for me as well. Thank you!!!

Can you remove the "model=generic" line, and instead try the latest upstream drivers as outlined here: https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS

With latest upstream drivers everything works..

Thanks, I assume it will then be fixed in the next release of Ubuntu.

Well, sorry to break it to you. None of those fixes work at all. If anything, I think I see some changes to GUI settings over changes to the fact my headphone jack doesn't work.

This is not fixed, sorry.

I confirm that the latest upstream drivers (alsa-hda-dkms_0.201112191418~oneiric1_all.deb) fixed the problem and now i can hear the sound from the headphones audio output on my Lenovo ThinkPad R61i laptop. Thanks!

Piotr Borkowski (boroslav-t) wrote :

I installed it on 64-bit system and it works. I think this package is compiled before installation.

Cool thanks, the driver plus adding line:

options snd-hda-intel model=generic

to /etc/modprobe.d/alsa-base.conf and a quick reboot has fixed the problem.

Shame this couldn't have come via an update.

Thanks for the heads up Piotr and linking my issue to this bug

Merry Christmas everybody :)

For me the line above was not necessary.

The dkms works partially. Yes the headphone started to work but the volume control behaves weird. I made a screen capture (see attachment) to show what's wrong. In this video I change the volume by the volume buttons on the keyboard. In a terminal window I have alsamixer running to see how the volume controls are influenced by this. What you see there is also what I hear: The volume decreases when the volume notification bar (at the top right corner of the screen) decreases from 100% to approximately 60%. In that range the volume of the headphone control descreases from 100% to 0%. Then from 60% to somewhere around 5% in the notification bar, nothing happens. And when the notification bar descreases from 5% to 0% then the PCM control decreases from 100% to 0%.

Marvin (marvin-nospam) wrote :

BTW: I guess the problem with controlling the volume I point out above, is more related to the user interface than the driver.

Why is the status of this bug report "incomplete"?

Changed in alsa-driver (Ubuntu):
status: Incomplete → Fix Released


Bug supervisors are the only people that can mark them as incomplete, I have now marked it as Fix Released.

Please attach your screen capture to the following Bug Report #909723 which I have created as I too have noticed that issue but now got round to opening a bug as there is a work around.

I upgrade to Precise, but:
 - alsa-hda-dkms is not present for precise
 - I uninstalled alsa-hda-dkms and phone doesn't work no more

@fain182, thanks for the information. Assuming you have the same hardware as the original reporter, could you please attach alsa-info (from a 12.04 installation) according to https://wiki.ubuntu.com/Audio/AlsaInfo ? Thanks!

here it is: http://www.alsa-project.org/db/?f=dc65b230989f00359d4bd52a187d04ddb208d068

( btw I found a workaround for precise, i installed again alsa-hda-dkms using the ppa for Oneiric on Precise.. )

David Henningsson (diwic) wrote :

@fain182, according to your alsa-info, you're running an old 3.0 based kernel. Make sure you run a 3.2 based kernel for precise. If you do that, I hope the problem will be fixed.
