Sound stopped working after upgrading to Linux 5.4 (Intel HD Audio)

Question

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.

Solution 1

Here is how I was able to resolve this:

1. sudo vim /etc/default/grub
2. Find GRUB_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")
3. sudo grub-mkconfig -o /boot/grub/grub.cfg
4. Reboot the system.

Solution 2

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.

Solution 3

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.

Solution 4

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 :

1. Updating /etc/default/grub with quiet splash in GRUB_CMDLINE_LINUX_DEFAULT.
2. Updating /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.

spelling : you meant 'alsactl' instead of 'aslactl'

[Biswapriyo]

Any explanation about that option?

[MiloMinderbinder]

HOW DO I UPVOTE THIS A BILLION TIMES? NOTHING OUT THERE WORKED AND I HAVE BEEN TO GOOGLE'S SECOND PAGE. THIS DID. THAT HOPE IN YOUR NAME MEANS SOMETHING SIR

After adding this option, do you still have microphone working?

[William Duclot]

I had to scour the internet for over 3 days before i found all this and painstakingly pieced it all together. It was excruciating!!

[William Duclot]

Please don't forget to upvote my question, too, as i did this just to save you guys my utter frustration.

[William Duclot]

@Biswapriyo I have no explanation. This is an arcane magick incarnation I pieced together from scouring the entire Internet, including kernel emails :-/

[RubenCaro]

Still no mic after this, only speakers. Any clue?

[CJ Maahs]

Works for me, but some people report they put the option in /etc/modprobe.d/alsa-base.conf instead, which seems less invasive than changing the grub configuration?

[William Duclot]

This saved my butt again on 20 October 2020.

[William Duclot]

This literally didn’t work for me. Doing echo snd-intel-dspcfg.dsp_driver=1 > /etc/modprobe.d/alsa.conf. The sound cards are completely undetected still.

IIRC, the file I found this is: github.com/torvalds/linux/blob/… When I tested it with some hardware no longer in my possession, I added it as a boot parameter modifying the grub config as described in the accepted answer and did not modify the alsa.conf

[davidparks21]

What needs to be run after this command for PopOS? I tried running that but I don't know what it's doing or what I should expect.

[armadill013]

@davidparks21 I added a command to check if it was appended (see above). You can delete it again with the command sudo kernelstub -d intel-dspcfg.dsp_driver=1 or sudo kernelstub -d snd_hda_intel.dmic_detect=0

[Raghavendra B N]

@hopeseekr Try echo "options snd-intel-dspcfg dsp_driver=1" > /etc/modprobe.d/alsa.conf instead.

[Admin]

I don't know why but this didn't work for me. The problem popped up after Jun 15 2022 update. as mentioned above I had to change alsa-base.conf as in askubuntu.com/questions/1169798/….
