    [SOLVED] Kubuntu 20.04 - Multiple Sound Outputs

    Hello Everyone,

    Moved from 18.04 to Kubuntu 20.04 today. I noticed that there are too many sound outputs in 20.04 and I have not connected my laptop to any headset or HDMI cable.

    In 18.04, there was only one sound output.

    My system info:

    Operating System: Kubuntu 20.04
    KDE Plasma Version: 5.18.4
    KDE Frameworks Version: 5.68.0
    Qt Version: 5.12.8
    Kernel Version: 5.4.0-29-generic
    OS Type: 64-bit
    Processors: 8 × Intel® Core™ i5-8265U CPU @ 1.60GHz
    Memory: 7.6 GiB of RAM

    Thanks,
    Avi

        Found a solution:

        (I could not sudo kate)
        sudo apt install gedit
        sudo gedit /etc/modprobe.d/alsa-base.conf

        Add this line to the end of the file:
        options snd-hda-intel dmic_detect=0

        ------
        Reboot system

          You don't need to "sudo" kate, just open the file normally in kate:
          Code:
          kate /etc/modprobe.d/alsa-base.conf
          It will ask for your password when you save the file (if elevated privileges are necessary to save the file)

              Hi,
              It is actually not an ideal thing to use kate with sudo, you should use nano that is already installed (Ctrl+O to save and Ctrl+X to quit).

              I tried the trick, but it did not work for me unfortunately.
              Kubuntu 20.04 on a ASUS rog strix z270f

              Moreover I tried this and it did not work:
              1. Edit /etc/default/grub
                sudo vi /etc/default/grub
              2. Find the line starting with GRUB_CMDLINE_LINUX_DEFAULT and append snd_hda_intel.dmic_detect=0 to its end. For example:
                GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel.dmic_detect=0"
              3. Update grub configuration
                sudo update-grub
              4. Reboot

              Still looking for a working solution. In the meantime I have to run killall pulseaudio to recover the sound output.
