[Thinkpad X60s] sound only from built-in speakers, not headpones

Jane,
     Thank you for reporting this bug. We are looking over the logging you sent. I have one question currently. Do your headphones have separate microphone/headphone plugs? I wonder if there could be something broken with your headphone connection in your laptop, but that is idle speculation until we finish looking through the logging.

Thanks!

Yes, there are separate microphone/headphone plugs. I also originally thought that it could just be a problem with the headphone connection, but don't think that's the case because the same thing happens no matter where I plug it in (e.g,. if I plug it into the laptop directly, or into the jacks that are on the docking station, or through the USB key thing). And I don't think it's the physical plug itself, because the headphones work fine on another computer.

Jane,
     My apologies, after reading back the description, you had indeed mentioned the dock. Would you mind attaching the output of an lspci command to this bug? I may have an idea on some way to test this based on the output.

Thanks!

~JFo

Apologies, I intended to add the full command line I was looking for in my earlier message, but I sent it before I did. :-)

Please run
'sudo lspci -vv'

and attach the output here. Sorry for the confusion.

Thanks!

I would ask that you test a new user and a Lucid LiveCD to test to see if the issue is reproducible.

David,
     from the initial bug report:

"DistroRelease: Ubuntu 10.04"

She is already running Lucid. and, per her comments, the issue is consistently reproducible.

Jane,

For easier debugging, we would like you to reproduce this symptom using the latest alsa-driver snapshot. Please add the ubuntu-audio-dev ppa[0], ensure that you are running 2.6.32-18-generic (from uname -r) installed, install linux-alsa-driver-modules-$(uname -r), then reboot.

Not directly related, but reading your machine's codec dump (Card0.Codecs.codec.0.txt) has revealed another bug (should be reported separately using ubuntu-bug alsa-base) that your PCM level is overdriven; the offset to 0 dB (which should correspond to 100%) is 0x3d, but the number of steps is 0x3f, which means anything set at 100% will sound distorted.

Jane,

Also, what Connector options are available in the dropdown menu in GNOME's sound preferences > Output tab?

I'll do what's suggested in comment #9 as soon as I get a chance. In the meantime, wrt comment #10, I don't have any connector options. Screenshot attached.

Okay, I did the stuff in comment 9 (added the PPA and installed linux-alsa-driver-modules). I wasn't running 2.6.32-18-generic when I originally reported the bug, but am now and can confirm that it still happens. Thanks for your help, and please let me know if there is other info I can provide!

Jane,

Thanks for verifying. We have two further debugging steps. Firstly, please append the following line to /etc/modprobe.d/alsa-base.conf:

options snd-hda-intel enable_msi=1

then reboot and try to reproduce the symptom. If you are able to reproduce the symptom, secondly, I have a patch queued that Brad can roll into a test snapshot of alsa-driver for you to test that adds jack change notification to your model.

I added the line as suggested, rebooted, and can still reproduce the issue.

Thanks, Jane. At this point it is unnecessary to retain the line added to /etc/modprobe.d/alsa-base.conf, so it's safe to remove it. I'm at work without access to my dev machine, but if you could reproduce your symptom using the most current live cd in the meantime, it would be much appreciated. I'll get the patch to Brad and/or Jeremy this afternoon.

We tried to reproduce this issue on a Lucid Beta 2 CD image and no sounds was outputted by the laptop (through speakers or headphones).

On an up-to-date Lucid, the issue remains.

Tried a live CD with Lucid (as of Beta 2, 8 April) and got no sound at all. No sound from speakers, regardless of whether headphones were plugged in or not.

With an up-to-date Lucid in a regular install, I still have the original problem (i.e, sound from speakers only).

Could you elaborate on "no sound at all"? Is the GNOME volume control showing a dummy/null output (or none at all)? If so, that's likely bug 557421.

@Jane,

Could you download and install the appropriate kernel from http://kernel.ubuntu.com/~bradf/bug_548661/. This has a patch from Daniel T Chen applied to it. You just need to download linux-image-$(uname -r)_2.6.32-20.30_i386.deb and then use "sudo dpkt -i linux-image-$(uname -r)_2.6.32-20.30_i386.deb" to install it. You will need to reboot after installing this new kernel.

I had not updated for several days, but when I did so today the problem disappeared. I'm not sure what fix landed when, but I'm currently on 2.6.32-21-generic and everything behaves as expected. :)

Forgot to add: thanks for your attention on this, and for whatever the fix is. I'm happy to help debug further if you want, but also comfortable if you want to consider this closed.

i has a same bug. 9.04 work fine after reinstall (not update) to 10.04 sound work just over speakers

Same bug happens to me too on a fully-updated Lucid system. It was working fine on Karmic a few months ago, on the same system (the relevant sound was flagged as "[Conexant CX20582 (Pebble)]" by the bug-reporting tool, the system itself is a Toshiba Satellite T110-107). Plugging in the headphones makes no apparent difference to the sound, which continues to come out via the speakers but not the headphones.

This bug possibly happened on Karmic too, relatively recently; I didn't report it at the time because I wasn't sure whether it had happened or not, and because I'm not sure exactly what happened then. (This bug isn't an obvious one to check for unless you're specifically paying attention...)

00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 60)

the same problem
Realtek acl655 based sound card.

mdyn,

Can you please try this out ?

on my Dell mini 10V I do lspci and I get the following information:

$ lspci -nn | grep Audio
00:1b.0 Audio device [0403]: Intel Corporation N10/ICH 7 Family High Definition Audio Controller [8086:27d8] (rev 02)

you need the 2 numbers in the [XXXX:YYYY] .. before (rev 02)

You need to run this command, replace XXXX and YYYY for the values on your machine.
$ pushd "/sys/bus/pci/drivers/HDA Intel/" && sudo bash -c "echo 'XXXX YYYY' > new_id" && popd

manually remove the snd-hda-intel module and install it with modprobe.

$ sudo modprobe snd-hda-intel

Let me know if your sound works after this, if it does please post the output of lspci -nnvv and other relevent information.

Since this bug was fixed for the original reporter, I'm marking it as "fix released". In order to minimize confusion: if you're still having a problem, it's a different root cause, and so I'd kindly ask you to file a new bug, e g by opening a terminal and entering the 'ubuntu-bug audio' command which will guide you through the bug reporting process. Thanks!
