After upgrading from Linux 5.3 to Linux v5.4.2 on Arch Linux, all of my audio stopped working. The only thing I see in Gnome 3’s Sound settings is “Dummy Output” and aplay --list-pcm says: “No card(s) found.” and running alsactl init says: “alsactl: init:1759: No soundcards found.”
I’ve tried many solutions already.
Here is how I was able to resolve this:
sudo vim /etc/default/grubGRUB_CMDLINE_LINUX_DEFAULT and add snd_hda_intel.dmic_detect=0 to the end of it. (ex: GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 snd_hda_intel.dmic_detect=0")sudo grub-mkconfig -o /boot/grub/grub.cfg
The option snd_hda_intel.dmic_detect=0 is deprecated on newer kernels, you may use snd-intel-dspcfg.dsp_driver=1 instead.
But be aware, it's slightly different meaning.
If you want to persist the kernel parameters (for example on Pop_OS!), you'll have to use kernelstub to append the parameter.
Either use sudo kernelstub -a intel-dspcfg.dsp_driver=1 or sudo kernelstub -a snd_hda_intel.dmic_detect=0 (depending on kernel version). Then you can check if it was appended with running the command sudo cat /boot/efi/loader/entries/Pop_Os-current.conf.
If you append the parameter directly it will get overwritten after rebooting.
Above solution by hopeseekr seems to be working for Dell G3 3590 with Nvidia GTX 1650 for newest ubuntu 20.04 installation in Dual Boot mode along with Windows 10. Initially there was no sound and no system brightness controller. I have tried following possible solutions by updating the grub but nothing seems to work :
/etc/default/grub with quiet splash in GRUB_CMDLINE_LINUX_DEFAULT./etc/default/grub with nouveau.nomodeset=0 in GRUB_CMDLINE_LINUX.Checking alsamixer in the the terminal was also not showing Intel sound card. Only Nvidia sound card was detected.
This has completely solved the problem. I have been searching for this solution since months. It detects the intel sound card correctly in Ubuntu 18.04 installation but was failing to do so in Ubuntu 20.04.
In Recent (i.e., post 2020) Fedora or RHEL derivatives, as superuser do:
This recipe assumes that you only lack being able to detect your physical device, therefore, the ALSA, lame, VLC, etc., drivers and/or plugins, plus other multimedia stuff, has already been installed by following other tutorials (if necessary) and your user is part of the audio group. A device name should appear if you type lspci -v | grep -A 7 -i Audio
This seems to be caused by the config option SND_HDA_INTEL_DETECT_DMIC being enabled in the 5.4 kernel (https://bugs.archlinux.org/task/64720).
The suggested fix is to undo the change by passing snd_hda_intel.dmic_detect=0 as a kernel parameter, as explained in this answer.
Current solution may be that:
add snd-intel-dspcfg.dsp_driver=0 in kernel parameters (/boot/grub2/grub.cfg to end of line linux or other places depend of your bootloader)
What worked for me, on Debian unstable with this sound card:
lspci -nn | grep -i audio
00:1f.3 Multimedia audio controller [0401]: Intel Corporation Sunrise Point-LP HD Audio [8086:9d70] (rev 21)
was
echo "options snd-intel-dspcfg dsp_driver=1" > /etc/modprobe.d/alsa.conf
With this option, it uses the legacy snd_hda_intel instead of SOF.
After running these 3 commands in a terminal I got sound working on HP Pavilion gaming laptop
echo "options snd_hda_intel dmic_detect=0" > audiofix.conf
sudo mv audiofix.conf /etc/modprobe.d/
reboot
For future seekers for the solution of the similar problem: the proposed solution with snd_hda_intel.dmic_detect=0 is probably wrong.
I had the similar issue and fixed it with installation of the sof-firmware package in my Archlinux.
The solution is described here.
Here is the citation with the description of what is going on and why dmic_detect=0 kind of helps:
sof firmware package was not installed and card therefore wasn't able to work in dmic mode, while using old dsp driver caused missing mic device as old driver does not support digital mic, Reverting settings in grub config to defaults and installing sof firmware package fixed the issue, Can be closed.
