Speaker audio channel goes mute after plugging in the headphone

Bug #921397 reported by Henrique Sant'Anna on 2012-01-25
This bug affects 13 people

Bug Description

Speaker audio channel goes mute after plugging in the headphone and unmute after the headphone is plugged out. By consequence there is no sound when trying to listen the sound by headphones.

This is a pulseaudio problem and can be circumvent by just editing /usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf and commenting the line as here:

#code = Headphone

This will avoid pulseaudio to change profiles when headphone is plugged in.

Some people affected by this bug don't get the headphones muted, but only a very low volume, this workaround could help too. But to some computer models this workaround could let the sound play by headphones and speaker by the same time (most people don't desire that).

On my computer model ( HP Pavilion DV-4 2080br ) the workaround works well and the sound goes only by the headphone, as expected.

If you mean the "Speaker" volume in alsamixer, that should not affect the headphone volume. You should be able to have sound through headphones even though "Speaker" is muted.

Could you clarify?

David H, I believe OP is talking about jack sensing auto-muting the speaker and does not find this desirable.

Henrique Sant'Anna (hsantanna) wrote :

Sorry about not being clear, my english is not that much good =)

By "Speaker audio channel" yes, I mean "Speaker" volume in alsamixer. It also mute the headphone output.

Seems that headphone ans speakers are muted/unmuted together by the sound card, by the same volume control.

The strange thing is that only the mute/unmute affects the headphone, but the volume itself at the Speaker control does not affect the headphone. The headphone's volume is controlled by it's own control in alsamixer.

I did more tests and here are some more curiosities:

When the Speaker control goes mute in alsamixer, the mute led goes mute/orange (even if the master volume control is not muted). When I plug in the headphone only the Speaker control gets muted but not the master volume (witch is expected).

If I go to the alsamixer and manually unmute the speaker volume, I get sound to headphone, but not to the speakers (witch is desired).

Now there is no muted volume/channel in alsamixer.

If I manually mute the Headphone volume while the headphone is plugged in, the master volume also gets muted and the led goes muted/orange. If then I unmute just the Headphone volume, the master volume don't get unmuted, there is no sound and mute led still mute/orange. Then if I unmute the master volume the led gets unmuted/gray ( witch is expected) but there is no sound to headphone, even with no channel muted: only when I change the Headphone's volume in alsamixer UP or LOW the sound comes back.

If I can do more tests or get more hardware info please just tell me what to do.


Henrique Sant'Anna (hsantanna) wrote :

So here is a clarification that I should have done when reported the bug...

Unespected behavior:

When plugging the headphone, speakers AND headphone output goes muted.

Expected behavior:

Only speakers goes muted, but not headphone output. After plugging headphones there should be sound at the headphones.

More details:

After plugging the headphone, at alsamixer the Speaker volume control gets muted (only this control) and it's volume goes to level zero: 0 <> 0
If I manually unmute Speaker volume at alsamixer, it's volume still at level zero and there is no sound to headphones. If I level UP the Speaker volume level I get sound to headphones and no sound at the speakers (wich is the expected behavior).

So what you're saying that if you currently have adjusted alsamixer so that you have sound coming out of your headphones:

 * if the "Speaker" volume is turned all the way down to -48 dB (without muting it, just turning the volume all the way down), suddenly your headphones mute.
 * if the "Speaker" is -47 dB your headphones are unmuted
 * if the "Speaker" is 0 dB your headphones are unmuted
 * regardless of "Speaker" is -47 dB or 0 dB, headphones have the same volume.

Is this correct?

Henrique Sant'Anna (hsantanna) wrote :

Yes, one workaround is*:

    1) plug the headphone
    2) open alsamixer
    3) and unmute (press M) at the Speaker control.

    * This have to be done every time after plugging the headphone.

Another workaround is**:

    1) Open in text editor the file /usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf
    2) Comment the line as here:
        #code = Headphone
    3) Save the file
    4) Restart pulseaudio with:
        pulseaudio -k

    ** This have to be done just once.

Answering your questions:

> * if the "Speaker" volume is turned all the way down to -48 dB (without muting it, just turning the volume all the way down), suddenly your headphones mute.

No, Skeaker volume level at alsamixer does not affect headphone at all. I was wrong when I said it before (about the -48 db), really sorry about that. The headphone output is affected by mutting/unmutting the Speaker control, but the volume level at this control does no affect headphone, not even at -48 db. Tested it again right now.

> * if the "Speaker" is -47 dB your headphones are unmuted


> * if the "Speaker" is 0 dB your headphones are unmuted


 * regardless of "Speaker" is -47 dB or 0 dB, headphones have the same volume.

Yes. Headphone volume is affected by it's own volume control at alsamixer, but not affected by the volume level at Speaker's control.

David Henningsson (diwic) wrote :

Actually a slightly better workaround would be to open

And change:

[Element Speaker]
switch = off


[Element Speaker]
switch = mute

...that way the port will switch, which means you can have different volumes for speaker and headphones, but "Speaker playback switch" will not mute when "headphones" is selected.

I have analyzed your issue a bit, but I'm unsure whether this is actually a bug in the codec hardware, or if it's related to the GPIOs. Marking as triaged for now.

I, too am affected by this issue, or at least an issue which quacks like this one.

I am using a samsung 7 series (700Z5A-S01), with a 3.2 kernel. For me, slightly different alsamixer values are reported (see attached file). Most notably, it reports my headphone as a sliderless control. For me too, headphone volume is controlled with the 'speaker' slider.

My workaround required a little bit more magic:

in analog-output-headphones
[Element Speaker]
; link to muting
switch = mute
; set volume to zero, so only the master slider controls playback volume. This gives better linearity.
volume = zero

The solution Ondergetekende (kvdveer) wrote also works for me on a similar model (700Z3A-S01) ubuntu 12.04 / 3.2.0-26-generic.

Happens to me after last update. ALSA 1.0.24 on Ubuntu 11.10. Before updating it was all fine (when the earphones are plugged the speakers get mute). After last system update, when I plug the earphones everything is mute, both speakers and earphones.

The first workaround I read (commenting code = Headphone) worked only the first time. After rebooting, it does not work anymore (I tried rebooting pulseaudio, disabling respawn, toggling the comment, etc.). Happens also when pulseaudio is off.

This is very annoying to me as I can't use VOIP (unless I use it with speakers, which of course produces echo in mic).

Whoops: my headphone broke somewhen during the tests. So please ignore the " does not work anymore" part.

I am having the exact same issue, and am also on an HP device. Problem started happening somewhere in the last month. Anyway I solved it with the following values for the Speaker Element:

[Element Speaker]
switch = mute
volume = zero

(note the 'volume = zero', which was not suggested in the comments above)
