I can confirm this. Using Hardy beta on a 2nd Gen macbook core 2 duo, the headphone jack outputs no sound at all, while internal speakers work.

I too can confirm this. Using Hardy beta 64 bit on a 2nd Generation MacBook. Internal speakers do work. All worked in Gutsy.

Polera (j-remash) wrote : | #7 |
UPDATE: Found a workaround.
1. Right click on volume control.
2. Click 'Open Volume Control'
3. Go to Edit --> Preferences
4. Check off 'Surround Sound'
5. Close Preferences
6. Un-mute 'Surround Sound'
7. Plug in headphones
That should do it (worked for me on a 2nd Generation MacBook as listed above)

mon (javiermon-deactivatedaccount) wrote : | #8 |
The workaround works here too. So the surround seems to control the headphones volume?

Polera (j-remash) wrote : Re: [Bug 201957] Re: no sound from headphones in macbook core 2 duo (2nd gen) | #9 |
Seems like. I wonder if it's more of a Gnome 2.22 bug.

Cannot confirm on 2nd gen macbook (core 2 duo). Headphone audio works out of the box for me (Hardy RC amd64), but Surround was also unchecked by default. Anyone with a similar result?

Leann Ogasawara (leannogasawara) wrote : | #13 |
I blieve Surround is un-muted by default now. Please reopen (ie set Status back to New) if this is not the case with the final Hardy release. Thanks.

I just upgraded to the final Hardy release on my Macbook and there was no sound from the headphones until I unmuted surround. The workaround works fine, though.

I just upgraded my 2nd Gen Macbook from Gutsy to Hardy and had the same issue (sound from the internal speakers, but none from the headphone jack).
The workaround recommended here (unmute the surround sound) worked great, though. Thanks for posting the solution, Polera!

Had the same problem on my 1-year old macbook with a fresh install of Hardy. The workaround worked for me.

It also makes sound from internal speakers much louder.

I confirm this bug and the workaround for 2.6.27-11 ubuntu kernel.
But the thing is my laptop is not macbook
It is Asus Z37S with HDA Intel sound.
The last version before the bug is 2.6.24-22-generic

Yes. Problem exists with the labtop Asus Z37S. Headphone plug in recognized, but with no sounds. Sound is only on the internal loudspeakers.
When looking at alsactl: headphone volume 00, and can not be increased....
Thanks.

Yup, the problem definitely still exists in Jaunty. I have a Macbook 2,1. The above workaround worked for me.

The problem is worse in Karmic. The sound preferences applet has changed and there is no surround option anymore.

Me too. Workaround worked in Jaunty. After upgrading to Karmic, sound no longer comes out of headphones, and it is impossible to follow the above workaround instructions.

but it didn't help.
I've checked the documentation:
/usr/share/
/usr/share/
/usr/share/
and edited /etc/modprobe.
options snd-hda-intel model=macbook
After reboot I had no sound at all.
Installing linux-backports
Still no sound on headphone jack.

Did you check your 'Surround' mixer setting?

Where can I find it? There is no Gnome mixer in Karmic as it was in
previous releases. Console alsamixer doesn't show the Surround item as
it was showing it in Jaunty.

Surround doesn't work on ubuntu karmic koala.
I don't know if the problem is coming from alsa or the mixer.
Maybe someone could try to install an old version of booth to try.

Charlie Herron (charlie-herron) wrote : | #52 |
I installed Karmic on my MacBook2,1 and was having the same problem, but I just ran alsamixer and messed around until it started working. Sorry that I don't have more of a concrete answer, but perhaps someone else can confirm what I *think* remedied the problem:
If you start alsamixer and tab until both playback and capture devices are listed, then scroll over as far right as possible, you should have Mux, Mux1, Speaker, Speaker1 on the right. I think I just increased the vol for Mux1 and Speaker1 (making sure they were both unmuted, of course). After that, transitioning from speaker to headphones worked as expected.
If you get it working this way, don't forget to 'sudo alsactl store' to keep your settings.

I can confirm this bug. I am in Karmic with a Macbook 2,1 and the headphone jack does not work. The alsamixer workaround did not work for me, and I see no way to unmute surround, though I'm fairly certain I did in Jaunty before I upgraded to Karmic.

S B (seuzy8) wrote : | #54 |
Okay, the following workaround works for me:
install gnome-alsamixer
uncheck the mute box on the second "speaker"
I don't know why it would have been muted in the first place.

It works!
And you don't even have to install gnome-alsamixer - the console
alsamixer can unmute the second Speaker - just press M.

mon, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://
If it remains an issue, could you run the following command in the development release from a Terminal (Applications-

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https:/
