I guess this question already had the answer here but I can't find it. I'm using 12.04.

Update:

The problem is that I can hear the sound from my laptop's speakers even I plugged in my headphones. Headphones is just standard stereo headphones. And the most interesting thing is that all was working just a week ago.

I tried to play with pulseaudio and alsamixer settings - no results.

What machine do you use? Netbook? Laptop? Desktop? Tell us the model and specification too, please. – audrianore Jun 14 '12 at 16:52
Also, if what you mean is that you get sound from both headphones and speakers at once when headphones are plugged in, I recommend editing your post to clarify that this is what you are saying. Also please let us know about whatever you've tried so far (if anything) to fix this problem. Also, is this the question you were thinking of? – Eliah Kagan Jun 14 '12 at 16:53

Original Solution

  1. Go to Realtek official site, accept the disclaimer, then download the audio driver for linux/unix. You need to select version 3 for Kernel 3 or later.

  2. Setup necessary tools to compile this driver.

    sudo apt-get install build-essential gcc make

  3. Extract the downloaded file, run sudo ./install file from a terminal after going to the extracted folder to compile the driver.

  4. Read the Readme.txt file for more information.

  5. Install gnome-alsamixer by this command.

    sudo apt-get install gnome-alsamixer

  6. Open the gnome-alsamixer by typing alsamixer in the dash.

  7. Select the "Auto mute mode" in the new window.

Reboot and see whether it fixed now. (Step 6 and 7 might not necessary). Automute will automatically enabled upon restart

Solution 2:

I have just found another solution:

(It worked for me with Only S/PDIF profile, Sound from both headphone and speaker and not being able to switch profile)

  1. Add this ppa by the command

     sudo apt-add-repository ppa:ubuntu-audio-dev/alsa-daily

  2. Update packages list. by 

    sudo apt-get update

  3. Then install "alsa-hda-dkms" package:

     sudo apt-get install alsa-hda-dkms

Reboot, And See the result!

I had exactly this problem. but it now fixed. you can install gnome-alsa-mixer to gain more control over your sound. Note that after compilation the sound will be muted. – Anwar Jun 14 '12 at 20:09
apt-get install alsa-hda-dkms has worked for me, thank you very much. – EarlGray Oct 13 '12 at 22:09

I also had this problem on my hp laptop. I found a post and take one of the advice, which suggests adding two lines to the bottom of the file /etc/modprobe.d/alsa-base.conf :

options snd-hda-intel model=laptop

options snd-hda-intel position_fix=1 enable=yes

save it and reboot. It works for me!

Had this issue on XUbuntu 12.04, reviewed this page, installed the gnome-alsamixer package, ran gnome-alsamixer, checked the "Headphone Jack Sense" option in the gnome-alsamixer GUI screen that came up, verified the problem is resolved. Thanks!

The command sudo apt-get install gnome-alsa-mixer did the trick for me on my Compaq nw8000.

I could enable the Headphone Jack Sense option and now it switches the audio to the headphone when I plug-in my head phones.

Try plugging in your headphones properly. This happened to me once and then after fixing that pin of the headphones correctly it worked properly.
