I got a Lenovo T440s and a docking station, where the docking station is connected to a monitor (specs) with internal speakers through HDMI.

My problem is I cannot seem to be able to change the audio output from the laptop speakers to my monitor´s speakers (as can be seen in the screenshot below, there is no HDMI option).

My laptop does not have a HDMI input, only my dock has. I suspect this is the reason why it is not detected and shown in the sound options.

Any help or insight appreciated.



sudo aplay -l

  • You probably need some drivers from the manufacturer. – Daniel Oct 8 '15 at 21:10
  • Not very helpful, but with my T430s and docking station, I definitely get an HDMI / DisplayPort 3 option for audio output... (and the T430s has no hdmi output either) – alci Oct 15 '15 at 12:44
  • Also, you can find information on thinkwiki.org (just in case you don't know of the site) – alci Oct 15 '15 at 12:50

In this window click on Analog Stereo Output.
There would be option like HDMI+Analog Stereo Output(or Duplex).

  • That option is not present, as the HDMI port on the dock is not detected – D-unit Oct 15 '15 at 12:21
  • Hi. What shows in terminal this command: sudo aplay -l ? – UNIm95 Oct 15 '15 at 12:29
  • updated original question with aplay output – D-unit Oct 15 '15 at 12:38
  • Try to add you in audio, video groups. Because by default in pavucontrol(program on screenshot) should be "Configuration" tab. There should be my solution. – UNIm95 Oct 15 '15 at 12:44
  • Tried adding my user to audio and video, didnt work. Still no HDMI – D-unit Oct 15 '15 at 12:59

Have you tried alsamixer?

Open up Terminal, then type alsamixer and press Enter.

You will get an odd sort of panel with all your output and input devices listed across the bottom, and a vertical display of the sound levels.

Left and right arrows pan through the list of sound devices, and up and down arrows increase or decrease the sound levels.

When you're dome making adjustments, just press Esc (the escape key) to exit.
