I have a Dell G3 15. Running Xubuntu 18.04. Everything was working perfectly until the 26/27th February 2020. After this the audio stopped working and I only see a dummy output in the mixer. Im guessing there was an update at this time. I think the Laptop has a ALC3204 sound card. I found that if I plug in a hdmi display I can play audio through the hdmi.

Things I have tried:

  • Reinstalled Pulse Audio and rebooted.
  • Disabled Secure Boot.
  • Opened the terminal and ran sudo apt-get install pavucontrol pavucontrol then entered configuration profile to set configuration to analog stereo out, only to find "dummy output" as the only option again.
  • Opened the terminal and ran sudo alsa force-reload.
  • pulseaudio -k && sudo alsa force-reload had no effect.
  • BIOS -> disable audio -> boot to Ubuntu -> restart -> BIOS -> enable audio -> boot to Ubuntu did not work. I still have "Dummy output" as the only sound output option.
  • I went onto the dell site to see if I could download a new driver for the Realtek ALC3204 but the only drivers that I could find on the site are only for Windows 10.
  • added "options snd-hda-intel model=headset-mic probe_mask=0x103" to /etc/modprobe.d/alsa-base.conf , btw this stops the hdmi audio working after a restart. So if i do this I have no audio no matter what I do.
  • I tried a USB audio "card" it works fine.
  • I just added, snd_hda_intel.dmic_detect=0 to this line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash mem_sleep_default=deep" in /etc/default/grub then ran update-grub and restarted. the headphone jack now works, speaker and mic still don't work.

Thanks for any help you can provide.


An additional kernel parameter may help see Audio broken.

Open /etc/default/grub as root and add 'snd_hda_intel.dmic_detect=0' to this line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel.dmic_detect=0"

after that execute

grub-mkconfig -o /boot/grub/grub.cfg

in terminal and reboot.

    Works like a charm. I needed to run alsactl restore before it worked though after rebooting Jun 16 '20 at 20:57

found the answer with some help. I asked someone who knows more than me and was pointed to this. How do I get sound with an HDA card?

It solved the issue.

Just in case that link disappears here are the steps followed.

open alsa-base.conf as root - e.g.:

sudo gedit /etc/modprobe.d/alsa-base.conf

and add the following lines at the end of the file

options snd-hda-intel single_cmd=1
options snd-hda-intel probe_mask=1
options snd-hda-intel model=basic
