So typically on most laptops, when the headphone plug is inserted into the headphone jack, sound to the internal speakers is cut off and plays through only the headphones. (This is the behavior in OS X, for example, and I believe it was also the 8.10 behavior.) I thought this was implemented in hardware, but apparently it's implemented by the sound driver, as Kacper's patch demonstrates. I think someone else already requested this above, but would it be possible to have a patch that mutes the internal speakers when headphones are inserted?
Also, and I believe this was also mentioned above, could we have a patch where Master controls the volume of the headphone output, too? Of course, this would only be useful if the above muting of speakers was implemented, as well. Kacper, are you the only developer working on this? Is anyone else involved with the ALSA project looking into this? -- Left speaker doesn't work, controls mixed up on Apple MacBook[Pro] (5,1) https://bugs.launchpad.net/bugs/337314 You received this bug notification because you are a member of Mactel Support, which is the registrant for Mactel Support.

In MacBook and MacBookPro 5,1 (aluminium, late 2008) the soundcard works out of the box only with headphones, and to turn speakers on it is necessary to manually set the 6 channels. In that case, sound is heard both on headphones and right and center speaker; the left speaker doesn't work yet.
