Ubuntu mutes speaker every time I insert something in the phone jack

  • 772

Every time I insert something in my phone output jack, the sound is muted and I have to go into alsamixer and turn up the volume on the Speaker lever.

I can see the reason this is so - when I'm listening in phones, I don't want the laptop speakers on - but my hardware does this for me automatically, and the Speaker lever goes to the phone jack when something is inserted there. The result of alsamixer doing this adjustment is that I have to open a terminal, type alsamixer, find the speaker lever and turn it up again, every time I insert something in the phone jack.

There has to be a way to turn off this behavior. But how?

  1. I found a way to do this!

    1. Start alsamixer:

      $ alsamixer

    2. Hit F5 to show all devices.

    3. Scroll to the right until you find Auto-Mute Mode. Set it to disabled.

    Done! My sound no longer mutes whenever I insert a plug in the phone jack!

  2. Which sound card do you have? A bug was reported recently.

    Potential solutions/workarounds:

    In your sound settings, try switching to analog speakers. It should look something like this:

    Analog

    Your other option would be to try the updated packages from the alsa daily snapshots:

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

    You will likely need to log out and back in, or perhaps reboot.

    This problem seems to be resovled out of the box in Ubuntu 12.04, without any (concious) action on my part. I guess that's a yay! =)
