I bought a new notebook and I'm having a hard time figuring out why it won't output sound over my wired headphones. The notebook is the Samsung Notebook 7 Force and I'm running Kubuntu 19.10.

It recognizes them as plugged in and pavucontrol display things as if the sound is being reproduced. There is nothing muted on alsamixer also. Sound work fine with the onboard speakers.

I also noticed that the driver searcher thingy in Settings doesn't show a list of hardware components, it only displays a message saying is getting information about the system (I don't know if it is related, I just thought it could have something to do with missing drivers).

Being a Dell user since, well, forever, I really thought wonky hardware support was a thing of the past.

sudo lshw -c multimediaoutput:

EDIT:

By setting the volume at 100% I can hear some sound: it is very low and it's played distorted, kinda like a buzzing sound.

EDIT 2:

HDMI output doesn't work also. This guy is having the same problem (S51 Pro is the model name of this laptop in Brazil).

  • Is your headphone jack compatible with your laptop. e.g. 3.5mm or 4.5mm

    It's 3,5 mm and I have tested a bunch of headphones, it's not the hardware, since it works on Windows. I've been almost five months stuck on this - and some - issues with this laptop with little help. I'm not trying to diagnose it or fix it anymore because I can't afford the time any longer. I did got back to Windows, unfortunately.

  • @wowbagger, can you try this? echo "options snd-hda-intel model=dell-headset-dock" | sudo tee /etc/modprobe.d/axr-audio.conf . Seems that the audio will work, but I'm not certain about the microphone.

Pain is over!

sudo apt install alsa-tools-gui
  1. Then, open HDAJACKRETASK
  2. Switch to REALTEK ALC256
  3. On "Black Mic Right Side" Check "Override" and select "Dock Microphone"
  4. Click Apply now (error message pops up)
  5. Install boot override
  6. Reboot

hdajack

Tried on Elementary OS.

When headset is connected go to sound options and just select proper options to use input/output from it.

  • Unfortunatelly, this doesn't work on the 20.04. Which, by the way, also doesn't work with the Intel Bluetooth/Wi-Fi combo card because reasons. So, yeah, Windows sadly.
