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.

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!

@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:/

@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 : | #8 |
@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.

Unfortunately not - we have already passed kernelfreeze (see https:/

@Nikola, there is now a way to upgrade your HDA drivers under oneiric, so you can follow the instructions here: https:/
...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://
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://
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://
This test is done with newest alsa-hda-
Should I report this problem upstream?
| David Henningsson (diwic) wrote : | #13 |
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:/
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:/
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?

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