Bug Description

When I plug in external speakers sound is lost. When I look at pavucontrol I can see that port is automatically changed from "analog speakers" to "analog headphones". If I manually set it back to "analog speakers" sound is back and is playing through external speakers. But every time I plug in the speakers this "automatic switching to analog headphones" happens and I am then unable to hear sound through external speakers.
In Natty this doesn't happen.

Definitely it is regression for me. I cannot use external speakers without manually changing output port.

David Henningsson (diwic) wrote on 2011-09-18:

What you have on the back - and that you plug your speakers in - is listed as a headphone jack, so the decision to switch to analog headphones is correct.

I think the problem here is that for some reason the same DAC is chosen to control both internal speaker and headphones jack. As a result the "speaker" alsamixer volume actually controls Headphone volume as well.

So I have the opposite bug where I plug headphones in and I don't get any headphone sound even though the System Settings has "noticed" that I plugged them in.

However if I manually change it back to speakers, with the headphones in, adjust the volume, change it to headphones and adjust the volume again, THEN I get correct volume in headphones and mute speakers, as it should be.

I think there's something broken with DAC selection as bugs #829843 and #830641 seem to be a very similar problem!

David Henningsson (diwic) wrote on 2011-09-19:

@Nikola, I have now run the codec in an emulator, and it seems like this problem is fixed upstream. I would advice you to https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules to try the latest upstream code - but those are not yet available for oneiric. :-(

David Henningsson (diwic) wrote on 2011-09-19:

@Zack, if you have different hardware, please file a different bug for your issue(s) as the root cause is likely different. Thanks!

Nikola Snele (n-schnelle) wrote on 2011-09-19:

@David, Thank you. When oneiric packages become available in the ubuntu-audio-dev ppa I will test it and report back.

I hope the fix will be available in oneiric final release though.

David Henningsson (diwic) wrote on 2011-09-19:

Unfortunately not - we have already passed kernelfreeze (see https://wiki.ubuntu.com/OneiricReleaseSchedule ).

@Nikola, there is now a way to upgrade your HDA drivers under oneiric, so you can follow the instructions here: https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS
...to see if that helps. Thanks!

@David, now I hear sound on external speakers. But I have new problems.

First problem: I set volume to 100%. But when I plug in speakers volume is not the same so I have to go pavucontrol and manualy increase/decrease volume. Video of the problem: http://www.youtube.com/watch?v=ps7_zLvHUpQ

Second problem: Sometimes after I unplug external speakers, volume (loudness) of sound on laptop speakers is very low although it is set to 100%. Video of the problem: http://www.youtube.com/watch?v=0ebnQ1m6knQ

Thank you for all the help.

First problem I reported in previous comment is maybe expected behavior.

But second problem is a bug. I made second (better) video describing the bug: http://www.youtube.com/watch?v=wqvZ7iwmTk8

This test is done with newest alsa-hda-dkms_0.201110091603~oneiric1_all.deb package from https://code.launchpad.net/~ubuntu-audio-dev/+archive/alsa-daily/+packages

Should I report this problem upstream?

Hi and thanks for your comments and videos.

The "second problem" sounds like a separate bug, compared to the original problem. It would make more sense to track it as a separate bug against PulseAudio for something like "missing alsa volume sync on port change, if volume is exactly 100%", with alsa-info's attached at all three places: before switching port, after switching port (here you experience the problem), and after moving the slider (which corrects the problem again).

That said, I'm not sure I have time to track it down right now; around release time a lot of bugs are being filed.

David, I followed your advice and have opened new bug report with alsa-info attachments : https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/878362
When you have time, please help me with this bug. I'll be patient.

Bug originally reported in this current bug report is solved by installing newest alsa package from https://code.launchpad.net/~ubuntu-audio-dev/+archive/alsa-daily/+packages.

Thank you.

Fabio, you're correct. It's the same bug. In addition, the kernel team are looking for volunteers to test the patch I wrote for that problem.
Any volunteers with affected hardware that would like to help out with testing?

Zack Evans (zevans23) wrote on 2012-01-04:

I have gone full circle. So over in my bug we have deduced that I can make different volume mixers work or not work correctly by forcing different "model" parameters.

This is equivalent to saying that there no suitable "model" for my complete hardware - or in other words - volume controls I see and DACs that the netbook actually has are not correctly mapped. Because really a "model" is a set of definitions of DACs and outputs.

So I will try the patch, try the build from the PPA mentioned above, and try changing the "model" parameter and make a matrix of how these interact.
