How to make HDAJackRetask work in Ubuntu 20.04?

  • 772

I am trying to use HDAJackRetask to fix some audio issues. However when I pick some overrides, tell the program to "Install boot override" and reboot I notice no changes and if I open HDAJackRetask again I see no overrides.

This happens on two different laptops running Ubuntu 20.04 with Kernels 5.4.2-050402-generic and 5.4.0-42-generic.

In journalctl I find this, which I guess might be the reason why this isn't working:

Does anybody know how to get this to work?

  1. It works for me renaming pulseaudio (autospawned parameter does not work):
    sudo mv /usr/bin/pulseaudio /usr/bin/pulseaudiodisabled
    killall pulseaudio
    then apply the HDAjackretask modification without reboot (you have to run alsamixer and unmute and raise master volume after apply ).
    Close alsamixer before testing another setting.
    As pulseaudio is disabled, play sound with audio program using alsa (speaker-test, mplayer, vlc...)

    then if errors persists , find which program blocks audio: sudo fuser -v /dev/snd/*

    If ok, install boot override , reboot, and test.
    if it is still ok, re-enable pulseaudio :
    sudo mv /usr/bin/pulseaudiodisabled /usr/bin/pulseaudio
    pulseaudio
