Kernel and sound issues

Hey all,

I've been having sound issues for quite some time with my laptop and figured it's time to ask for help.

Anytime the kernel has been updated (ie: 5.3.12 -> 5.3.13 or 5.3.13 -> 5.4.1), I am unable to play any sound on the most recent kernel. I've been forced to downgrade the kernel to the previous version to play sound. This includes kernels that previously had no sound (ie: I get sound on 5.3.13 perfectly now). When attempting to check/set sound options through pavucontrol, the audio stream will show activity when playing a song, but no sound comes from the speakers. As expected, running speaker-test provides no sound either. No speakers are muted in alsamixer, nor is the sound volume set too low either.

Some additional research showed me a common trend with sound and the snd_hda_intel.dmic_detect=0 option needing to be set. Unfortunately, setting the option in the bootloader causes no sound card to be detected, an inability for pavucontrol to connect to pulseaudio, and no sound options in the gnome sound panel. I'm currently working my way through the wiki's sound troubleshooting page in hopes of finding something new. Does anyone have any advice on something to try?

Re: Kernel and sound issues

I'm updating this with some more information from troubleshooting and I've come across some other interesting things that may or may not be related.

  • Using the LTS kernel breaks sound even more completely, removing all options for sound

  • It's possible to have sound through bluetooth when on the most recent kernel.

  • Plugging headphones into my headphone jack does not work no matter the kernel version (maybe broken?)

  • Waking from a suspend is impossible on the most recent kernel (different issue I assume, just putting it here for my future diagnosing)

Pulseaudio does start on login

$ systemctl --user pulseaudio

amixer finds the cards and does show them as being on

$ amixer

  Limits: Capture 0 - 65536
  Front Left: Capture 65536 [100%] [on]
  Front Right: Capture 65536 [100%] [on]

alsamixer init claims that the card is being initialized with a generic method, which appears to be pretty much par for the course with it.

$ alsamixer init
alsactl: sysfs_init:48: sysfs path '/sys' is invalid

Found hardware: "HDA-Intel" "Realtek ALC1220" "HDA:10ec1220,155897e1,00100003 HDA:8086280b,80860101,00100000" "0x1558" "0x97e1"
Hardware is initialized using a generic method
/usr/share/alsa/init/default:263: value write error: Input/output error
/usr/share/alsa/init/default:263: value write error: Input/output error

Because I've seen some recommendations to restore/store settings with /usr/bin/alsactl, I tried that next. Restarting the first time had all sound cards missing, restarting a second time has my headphones considered perpetually plugged in.

$ sudo /usr/bin/alsactl restore
[sudo] password for ephreal: 
/usr/bin/alsactl: set_control:1461: Cannot write control '2:0:0:Headphone Playback Switch:0' : Input/output error
/usr/bin/alsactl: set_control:1461: Cannot write control '2:0:0:Capture Volume:0' : Input/output error

$ sudo /usr/bin/alsactl store
$ sudo /usr/bin/alsactl restore

Some more general information now that I know a little more what commands to use and what might be useful.

Re: Kernel and sound issues

What are you using to actively check whether sound does or doesn't work? When the not working situation arises what are your outputs for 

sudo fuser -v /dev/snd/*
aplay -lL
amixer -c0
pacmd list-sinks

Re: Kernel and sound issues

Hi V1del,

I've been keeping an eye on pavuctl's playback, which does register sound as being played. No sound comes out of any speakers though. Currently pavuctl claims that headphones are plugged in and available (although they do not work) and speakers are unavailable.

Here's the output from the commands while trying to play something with no sound coming through the speakers.

sudo fuser -v /dev/snd*

$ sudo fuser -v /dev/snd/*
