[Lenovo IdeaPad Y550A] Subwoofer don't mute/unmute on plugging external acoustics

[RussianNeuroMancer]

Binary package hint: pulseaudio

On Kubuntu 10.04 (ALSA only) I when I put headphones - speakers muted automatic.
On Ubuntu 10.10 (with PulseAudio) when I put headphones subwoofer still continue to sound until I select "Analog Headphones" channel instead of "Analog Speakers" channel in system sound options.
Tested on Intel HDA (in my case it's Realtek ALC272 chip).

== Regression details ==
Discovered in version: maverick
Last known good version: lucid

Is there an "Analog Output" selection in the dropdown?

[RussianNeuroMancer (russianneuromancer)]

Yes. When it's selected only headphones work.

[David Henningsson (diwic)]

Hi RussianNeuroMancer and thanks for helping us test the upcoming release of Ubuntu!

I've trying to analyze your problem and notice that on HDA node 0x0C, the speaker is disabled. I don't understand how this can be though, because when the chip is set up, the node 0x0c should be initialized correctly.

Anyway, if you open "alsamixer -D hw:Intel", there should be a "speaker" bar, that you could try muting and unmuting (press the "M" button). Does that help?

I also analyze issue deeper and found something funny.
In sound option selected "Analog Speaker" output.
1. Headphones not attached. I try to playback music. It's sound from speakers. All is fine.
2. Headphones is attached. I try to playback music. Music sound from headphone and... laptop subwoofer!
Laptop model: Lenovo Y550-4CWI.
Maybe it's not PulseAudio bug, but ALSA? Or still PulseAudio bug?

Yes.

[David Henningsson (diwic)]

It's an ALSA bug. We need to figure out what node the subwoofer actually has, likely it is NID 0x15, but we need to verify that.
You can try doing this with hda_analyzer, it's available in the snd-hda-tools package in ubuntu-audio-dev's PPA. Do you know how to use hda_analyzer?

[RussianNeuroMancer (russianneuromancer)]

> It's an ALSA bug.
Not just a bug, but regression.

> Do you know how to use hda_analyzer?
No. Maybe tutorial somewhere?

Also, because few annoying bugs, I back to Lucid currently. I can continue test Maverick only next week, after Beta is out.

[RussianNeuroMancer (russianneuromancer)]

I check ubuntu-audio-dev ppa, but package snd-hda-tools not available for Maverick.

You can add package for Maverick to this PPA?

[David Henningsson (diwic)]

Yes, it's right here: https://launchpad.net/~diwic/+archive/maverick

[RussianNeuroMancer (russianneuromancer)]

> likely it is NID 0x15, but we need to verify that
How I can veriy that?

I also attach screenshot of NID 0x15.

[David Henningsson (diwic)]

You can click both the "Mute" checkboxes and see if either one mutes the subwoofer.

[RussianNeuroMancer (russianneuromancer)]

Thanks!
I check - subwoofer is NID 0x17.

Now possible fix this issue?

[David Henningsson (diwic)]

Cool! I have a first version of the patch here. First make sure https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules is *not* installed. Then install
http://people.canonical.com/~diwic/temp/alsa-intel-hda-update-diwic-ideapad-y550-dkms_1.0.23_all.deb
and reboot. Please report back whether it fixes your problem or not. Thanks!

[RussianNeuroMancer (russianneuromancer)]

I can not install this package.
make.log attached.

[David Henningsson (diwic)]

Okay, I can reproduce that error here. Here's how to fix:

First:

sudo apt-get remove alsa-intel-hda-update-diwic-ideapad-y550-dkms

Then check if there are traces left with

sudo dkms status

If there are still traces (shows up as "alsa-intel-hda-update-diwic-ideapad-y550, 1.0.23: added" ), do:

sudo dkms remove -m alsa-intel-hda-update-diwic-ideapad-y550 -v 1.0.23 --all

Then download and install http://people.canonical.com/~diwic/temp/alsa-intel-hda-diwic-ideapad-y550-dkms_1.0.23.diwic_all.deb
Reboot and retry. Sorry for the inconvenience.

[RussianNeuroMancer (russianneuromancer)]

Thanks for this patch!
With this version of ALSA issue is fixed.

[RussianNeuroMancer (russianneuromancer)]

Can you please check another regression-potential bug? https://bugs.launchpad.net/ubuntu/+source/linux/+bug/606839

[David Henningsson (diwic)]

Cool. The good news is that upstream has accepted the patch. The bad news is that it contains fixes to generic stuff which makes me unsure whether this can go into Maverick or not.

In other words, a few days from now, it should work with upstream snapshot according to: https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules

For bug #606839, I don't know much about network drivers, so I'm not the one to look into it.

[RussianNeuroMancer (russianneuromancer)]

Please check same bug with Acer Aspire 8943G laptop: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/656625 (probably same easy fix can be applied for this laptop).

[RussianNeuroMancer (russianneuromancer)]

Since the manufacturer has made some changes to the their product classification I rename bug. Lenovo support say Y550 and Y550A are similar in many aspects, but I think do a clarification was necessary.

[Jean-Baptiste Lallement (jibel)]

David, has the fix landed in maverick ?

[bm (bmpinky)]

Hi everyone. Newbie on Ubuntu and I had the same problem on a HP-Compaq Desktop Small Form Factor. Where or when can I find a patch? Thank you.

[David Henningsson (diwic)]

@Jean-Baptiste, no. For faster processing, see

@bm, if you're having different hardware, please file a separate bug - open up a terminal window, then enter this command:
ubuntu-bug audio
...and follow the instructions.
Thanks!

[Jean-Baptiste Lallement (jibel)]

Thanks for the update. Marking as triaged then.

[bm (bmpinky)]

Hi, it's me again. Workaround I used is putting on Sound Preferences/Output/Connector to "Analog Headphones". And "mute" on alsamixer/Speaker.

[RussianNeuroMancer (russianneuromancer)]

@bm follow comments 6. 9, 11 for find right PIN. After that create different bug report.

[madbiologist (me-again)]

This bug is fixed upstream in kernel 2.6.37-rc1. From the changelog:

commit 6cb3b707f95954ac18f19b4b3919af235738371a
Author: David Henningsson
Date: Thu Sep 9 08:51:44 2010 +0200

    ALSA: HDA: Add fixup pins for Ideapad Y550

    By adding the subwoofer as a speaker pin, it is treated correctly when auto-muting.

    BugLink: https://launchpad.net/bugs/611803

A PPA of this kernel is available at http://kernel.ubuntu.com/~kernel-ppa/mainline/

[madbiologist (me-again)]

This bug is now also fixed upstream in linux kernel 2.6.36.2.

[Martin Pitt (pitti)]

Accepted into maverick-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Steve Conklin (sconklin)]

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

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 https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[RussianNeuroMancer (russianneuromancer)]

I enable proposed yesterday, but there no any alsa related packages in proposed. I try to install all proposed packages, but bug is still present.

Are you sure that the fix is in the proposed?

[RussianNeuroMancer (russianneuromancer)]

> but there no any alsa related packages in proposed
And, sure, I recheck it five minutes ago.

[Martin Pitt (pitti)]

This got fixed in the linux kernel, not in alsa-driver. Fixing task.

[RussianNeuroMancer (russianneuromancer)]

Today I get new updates from proposed. There is new chromium-browser build, new linux kernel (something about omap in changelog), but there is nothing about this bug. After apply this updates problem still here.
I not sure, but looks like fix not in proposed, or now fix not work for me.

[David Henningsson (diwic)]

Could you make sure that you're running version 2.6.35-25.43 of the kernel and that you have no alsa driver updates (or dkms updates) that might interfere?

[RussianNeuroMancer (russianneuromancer)]

1. Currently I have 2.6.35-25.43 kernel on this laptop.
2. No special alsa driver updates. Package from commentary #15 is removed.
3. In dkms status I see only nvidia modules.

[Brad Figg (brad-figg)]

This patch was applied to Maverick as part of an upstream stable update, therefore it doesn't require individual verification.

[David Henningsson (diwic)]

@RussianNeuroMancer, that's strange. Can you supply an alsainfo ( https://wiki.ubuntu.com/Audio/AlsaInfo ) for further analysis? Thanks!
