Bug 81580

you have to post the output of alsa-info.sh

the auto mic selection is performed by the driver when the headset Mic use the Jack state of headphone

do you mean the driver does auto swtich the input to headset Mic when heafeet is plugged

seem auto Mic selection is disabled when there is capture source control to select input source

this cannot be solved by pulseaudio in user space, 

there are some laptop (e.g. DELL alienware) which have headset, hp and Mic jacks 

https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1302090

https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1332900

only driver know which one is headphone or headset if you want to enable auto Mic with internal Mic, headset Mic, dock mic or dock headset mic

So it is not pulseaudio who switching output port based on jack detection, but kernel driver?

when there are two detectable mic JacKS and internal Mic, 

there is no way to know the user want to use which input sources when both Mic jacks are plugged



if you really want auto Mic between headset Mic and internal mic if you notebook does not support conventional Mic jack

modify driver to create a headset Mic Jack which return the Jack state of headphones and don't create the headset Mic phantom jack


and use hda Jack retask to remove dock mic to enable auto mic




there are hda codec which only have one playback volume control but no headphone playback switch nor speaker playback switch

driver can perform auto mute by gpio or using pin ctl

What I want is to have some consistency. If I plug headphones (mic+output) into jack I want to set either both parts (mic+output) or none as default audio device.

Now when I plug headphones into jack, only audio output is switched for using from internal speakers into jack heaphones.

It is really stupid if I have active conference call (and using internal mic+internal speakers) and I plug headset (intput+output) into jack and only audio output is automatically switched from speakers to headphones... Mic should too.

to enable auto Mic, the codec need to differentiate between  the headset and headphone

you have to provide out put of debugged version of alsa driver which show the headset is set to which modes : headphone, iPhone style headset, Nokia Style headset, Mic in

dirty workaound is to change to use headphone Jack to change the headset Mic if the notebook only support headset and don't support headphone

from user point of view, i will expect the driver initialize the Jack as Same as the icon next to the Jack

for desktop, those rear Mic and line in can be retasked as output to support surround5.1

for netbook, the headphone can be retasked as Mic.  

for those notebook with three/four jacks , those input jacks and headphone jacks can also be retasked as line out jacks to support surround 5.1/7.1

yes, it is the kerenl driver perform auto mute, pulseaudio just use the Jack detection control to find out which volume control of the selected audio path

in your case,  you may need to give up the support of headphone by using a new hint to force the driver to support headset only  when the codec cannot differentiate headset or headphone

the alternative way is to use what did you plugin to select the headset or headphone when ever you plugged

So what to do? Do you need some other logs? Or cannot be auto mic switch implemented?

have you ask David who implement headset mic for dell notebook alsaid driver ?

https://bugzilla.kernel.org/show_bug.cgi?id=76611

it seem that  none of dell notebooks can dintinguish headset and notebook

but there are dell alienware notebook which have three jacks : headset, headphone and Mic jack

those alienware users are expect they don't need to use the pop up dialog

does the playback work with dock line out, it seem that dock line out and internal speaker share dac and pcm playback volume

I do not have dock/port replicator so I cannot test how it will work.

the driver should document if the capture source is really used for switch the function of combo jack

this is the only headset Mic with sequence number 0x0c support Jack detect but does it really imply that it is capable of distinguish headset and headphone

Have you read the link Raymond pointed to:

http://voices.canonical.com/david.henningsson/2014/03/07/headset-jacks-on-newer-laptops/

We don't know if you plugged in a headphone or a headset, so the best we can do is to pop up a dialog asking you what you plugged in, so you can select "headphone" or "headset" by a simple click of a button. Which is what we do in Ubuntu 14.04.

(I was investigating whether to do some of this GUI related stuff in PulseAudio instead so it could help users of other distros as well, but Tanu was hesitant to adding GUI related stuff in PulseAudio.)

If I understand correctly, you wrote that it is not possible to autodetect if device is headphone (line out) or headset (line out + line in), right?

But when I plug my old Nokia headset which has 4 pin jack (last pin is ground and it has both mic input and speakers output), kernel autodetect that something was inserted and automatically switch input from internal mic to jack mic.

So somemthing now detected that headphones with microphone was inserted... So why cannot be that autodetection used also for switching audio output from internal laptop speakers to headset jack?

Also I tried normal headphones (without mic, 3 pin jack) and nothing switched microphone input. So really HW/kernel/PA can somehow distinguish between headset and heaphones -- because I see in PA port config that input is automatically changed when I plug/unplug Nokia headset.

Or I missed something?

Ok, this is confusing. Could you post alsa-info for both scenarios
1) with headset plugged in
2) with headphones plugged in?

...and we could compare them for differences?

alsa-info with nokia jack

This is interesting. Now I used older kernel version, but from ubuntu repository (3.13.0-32-generic #57~precise1-Ubuntu) and when I plugged nokia headset now it automatically siwtched both output and input to jack.

I'm sure that before only mic output was automatically switched and from first attachment I see that it was on upstream kernel 3.16.

So ubuntu kernel in precise has some patches which are not in upstream 3.16 which enable autoswitch also for output (not only mic input) -- or that autoswitch for output is broken in new kernels.

Now I do not have any classic 3 pin jack headpnes (without mic) to test, so if you need output from alsa-info please wait some time...

To double check, could you compare headphone and headset plugged in, on the same kernel version? To see that something actually reacts differently?

to switch between headphone and line out, the driver  need to change EAPD and pin ctl from OUT HP to OUT 

so change the capture source is not suitable for changing the role of the combo Jack:


so far it seem  none of those 4 pin combo Jack support to use as line in


but three pin Mic Jack can be switch to line in using the Mic Jack mode control by adding hint add_jack_mode

i think Palo expect his headset mic can work like those iPhone headset connected to macbook air , those Jack is dedicated to headset and does support headphone nor microphone

how about hacking headset-mic.conf use headphone jack 

but this mean you cannot use normal headphone or mic


http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa/mixer/paths/analog-input-headset-mic.conf



[Jack Headset Mic]
required-any = any

[Jack Headset Mic Phantom]
state.plugged = unknown
state.unplugged = unknown
required-any = any

[Jack Headphone]
-state.plugged = unknown
+required-any=any

what I expect is that if I connect headset (input+output) to jack then pulseaudio automatically switch input+output from internal mic+speakers to headset connected to jack.

Now I tested 3.17-rc6 kernel and it switch only speakers output to headset. Microphone input was not switched. But it worked with ubuntu kernel (3.13.0-32-generic #57~precise1-Ubuntu).

So ubuntu has some special patch for it which is not in upstream kernel, or there is regression, it worked with older kernel but not with new.

I uploaded new outputs from alsa-info.sh script. I tested it on Ubuntu 12.04 Precise release with lastest precise kernel 3.13.0-44-generic and also with new upstream kernel 3.19-rc1. Each test file has suffix:

* combo: connected both microphone (3 pins) and headphones (3 pins) via special reduction (4 pins) to jack port
* disconnected: nothing was connected to jack port
* headphones: standard headphones (3 pins) was connected to jack port
* microphone: only (stereo) microphone (3 pins) was connected to jack port
* nokia: Nokia Headset (headphones + microphone) (4 pins) was connected to jack port

Are these logs enough for analyze? Do you need something more?

So, if I understand you correctly, with the alsa-info.3.13.0-44-generic kernel, the system reacts differently depending on whether you plug in headphones or headset combo.

So I did a "diff -u alsa-info.3.13.0-44-generic.headphones alsa-info.3.13.0-44-generic.combo", but I couldn't see any differences that could result in PulseAudio reacting differently w r t jack detection.

In both cases (headphones and combo) under 3.13.0-44-generic pulseaudio changes audio output when jack is inserted. But do not change audio input when combo is plugged. So I think that system reacts in same way.

But "diff -u alsa-info.3.13.0-44-generic.headphones alsa-info.3.13.0-44-generic.combo" contains some differences in "Converter:" lines.

But in comment #29 you say that the system reacts in a different way depending on whether you plug in headphones or headsets. And that is what we are trying to verify here. But now you say they are reacting the same?

The converter numbers are initialized on first playback/record. If they are zero, it probably means you have not had a stream running to/from the codec since the sound driver was last initialized (which usually happens on boot only, I think). They are unrelated to jack detection.

I said that:

And I remember that pulseaudio really switched input to jack mic.

But now with same Nokia headset and with pulseaudio 5.0 and kernel 3.13.0-44-generic input is not switched.

So something must have been changed in kernel or pulseaudio since I did that tests. Otherwise I cannot explain different behaviour in past and now.

Ok. If you can find a configuration (PA, kernel, etc) where the system acts differently between headphones and headsets, please submit alsa-info for those two scenarios.

If you can't find it, I think we should close this bug.

as the combo jack cannot differentiate headphone, headset , headset mic phantom jack is  created

you have to give up the support of headphone in order to allow headset mic can be auto selected

use jack sense of headphone pin to represent both headphone and mic . need to modify dfriver to create headset jack instead of headphone jack and headset mic phantom jack

I'm not sure I get understand the NEEDINFO state of this bug. What information is still missing? Currently on my Gnome 3.20 desktop, I'm also confused by needing to manually switch Input Device to Headset microphone for business calls, running pulseaudio-8.0 (has been the same for many previous versions, if not always). 

Why wouldn't pulseaudio automatically do this for me? Windows drivers seem to have no problems.
