I've developed a patch against alsa-driver-1.0.22.1 which should fix this (which I've attached to this bug), which you can test as follows:
First make sure you don't have any versions of linux-backports-modules- alsa installed: apt-cache --names-only search linux-backports-modules-alsa | cut -f 1 -d ' ' | xargs sudo apt-get remove --purge Now download alsa driver source and the patch, and compile and install a patched version of the driver: cd ~ wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.22.1.tar.bz2 wget http://dl.dropbox.com/u/174251/alsa-driver-1.0.22.1-mb5.patch tar xjf alsa-driver-1.0.22.1.tar.bz2 patch -p0 < alsa-driver-1.0.22.1-mb5.patch cd alsa-driver-1.0.22.1 ./configure make sudo make install Now you need to reboot your machine. If this works I'll push the patch upstream and hopefully we can get it applied to linux-backports-modules- alsa as well. ** Attachment added: "Patch to enable speaker muting when headphones inserted on MB(P) 5,1 / 5,2" http://launchpadlibrarian.net/37844781/alsa-driver-1.0.22.1-mb5.patch -- Speakers not muted when headphones inserted (Macbook 5.1, late 2008) https://bugs.launchpad.net/bugs/480796 You received this bug notification because you are a member of Mactel Support, which is the registrant for Mactel Support. Status in The Linux Kernel: New Status in Mactel Support: New Status in “linux” package in Ubuntu: Confirmed Bug description: Hiya, The title pretty much says it. When I insert headphones into the jack on my laptop, the external speakers are not muted and the headphones are not activated. I have to lower the master volume to the minimum level (not 0 as this mutes all outputs) and raise the headphone volume. This should be done automatically. - Jack sense should work - Adjusting the master volume should also adjust the headphone volume (providing that the speakers are correctly muted...)
