When I plug headphones into the headphone jack in Ultra Dock on my W540, I don't have any sound.

I have tried the proposed solutions for T420s mentioned in this post , none of them worked for W540.

Is there a way to make the external headphone jack on the Ultra Dock work with Ubuntu? I have 15.04 with kernel 3.19.0-26.

Solution: Use HDAJackRetask tool from alsa-tools-gui package.

  1. Install alsa-tools-gui package that contains HDAJackRetask.

    sudo apt-get install alsa-tools-gui

  2. Launch hdajackretask from the command line or unity launcher

  3. From the drop-down menu at the top, choose Realtek ALC3232 as the codec.
  4. Check show unconnected pins and Advanced override options from the right sidebar.

  5. Look for the entry with Pin ID: 0x16 and check Override. enter image description here

  6. Use the following options for overriding:

    • Connectivity: Jack
    • Location: External
    • Device: Headphone
    • Jack: 3.5 mm
    • Color: Green
    • Jack Detection: Not present
    • Channel group: 3
    • Channel (in group): Front
  7. Click Apply now to test new settings.
  8. Finally after making sure it works, you may persist the settings by clicking Install boot override. This will make sure your settings will be loaded with every boot.
