I was playing music with my headphones plugged in. The music was coming out of the headphones, but I also noticed that my speakers were playing the same music.
Why is this, and how can I fix it?

This answer helped me to get rid of this problem. My card was an Intel card.– AnwarSep 23, 2012 at 3:23

This is probably an alsa issue. I had the same problem, but it got reported as a bug and fixed.

+1: This is an ALSA bug. In addition to whatever workaround you can get, please file it - our audio maintainer is pretty good with these :) The driver needs to have a correct mapping of all the various inputs your sound hardware has - one of which is a “you've got headphones plugged in” signal - and not all systems have correct mappings. Running “ubuntu-bug” should get you the symptoms-based reporter, where you can get the relevant audio logs to a bug.– RAOFJul 29, 2010 at 2:58

It has worked for me since the upgrade to 10.10 on hda intel platforms. the previous solution was to open sound preferences, which triggered a probe and changeover to headphones. in my opinion, not a bug...tradeoff for speed increase by not polling the interface Nov 29, 2010 at 21:03
I had the same issue. It appears that the new kernel did not correctly detect the sound card model that you have. You will have to edit the /etc/modprobe.d/alsa-base.conf file and set the model manually with
options snd-hda-intel model=<model>
Unfortunately, finding the correct sound card model can take a little guess work. I took me several tries to find the sound card model that would detect the headphones correctly.
This link gives a list of sound card model: http://ubuntuforums.org/showthread.php?t=1043568
More information can be found on the Ubuntu Wiki.

If you have to do this, file a bug too; the kernel should detect the module automatically. Jul 29, 2010 at 5:57
