Audio quits after startup sound -Fedora 41

Ask Fedora
1

I’ve been troubleshooting this for weeks and am finally reaching out for help. I got a 1 year old laptop (Lenovo Legion 7 Pro) off eBay, dual boot, and Win11 has no issue with audio on this machine, so I don’t think it’s a hardware problem.
Upon booting Fedora 41 KDE, it always plays the startup sound, but then afterward if I launch, say, Firefox, and start to play a youtube video, sometimes I’ll have audio and sometimes I won’t. It’s a tossup. If I do have audio, then if I pause/stop the video and wait a few minutes and then resume, then I may or may not have audio upon resume. I can see the meter levels moving in the Sound System Settings menu, and the little taskbar icon that shows what’s currently playing is running visually as if it’s playing, but no sound is coming out of the speakers. Then after reboot, same thing- I hear the startup sound just fine, but dice roll if I’ll have audio after that. Just fyi I did previously try Kubuntu on the same machine and it had the exact same issue, although I was able to run “sudo alsa force-reload” and it would consistently fix it but only temporarily for maybe a few minutes, not sure why. But Fedora doesn’t have the alsa command. It’s a fresh install of Fedora, updated as of today, open-source graphics (I have NVIDIA card but have not installed the non-free driver), the only thing I’ve done after the fresh install so far besides update is install inxi and run “sudo dnf install alsa-firmware”. When I installed the alsa firmware it fixed the problem temporarily, but then after reboot, same thing- startup sound played fine but no audio after that. I’d love to have consistent audio on this laptop.

Any help you could give would be greatly appreciated! :slight_smile:

Is it just auto-selecting the wrong output device? Maybe you can use wpctl status to see what default sink is set and/or wpctl set-default <N> to configure the default that you want?

3

I ran wpctl status when the issue was happening, and then ran it again when the audio was working, and it’s using the exact same sinks and default sink in both scenarios.

I just now discovered though, that closing the lid to the laptop so that it goes to sleep, then reopening, will consistently bring the audio back. Of course, it’s only a matter of time before it quits again.

It sounds like it might be another power management bug. Sometimes disabling power management on specific devices or setting the power profile to “performance” will work around that sort of problem. Using an older kernel until the problems are worked out is another work around that some people are using.

It looks like the snd_hda_intel driver has three power management related tunables:

$ modinfo -p snd_hda_intel | grep power
power_save:Automatic power-saving timeout (in second, 0 = disable). (xint)
pm_blacklist:Enable power-management denylist (bool)
power_save_controller:Reset controller in power save mode. (bool)

It looks like the power_save option defaults to 10 seconds:

$ cat /sys/module/snd_hda_intel/parameters/power_save
10

Is 10 seconds about how long your sound works before cutting out?

You should be able to adjust that setting (temporarily, until you reboot) by running something like echo 60 | sudo tee /sys/module/snd_hda_intel/parameters/power_save.

Yes, it is roughly 10 seconds between the time any audio last played and when it won’t play any more. Like if I’m playing music on youtube, then pause, I can restart it in 5 seconds and audio works, but after ~10 seconds it won’t have sound until a reboot or sleep/wake. I adjusted the power_save per your recommendation from 10 to 60 but no affect. I tried a value of 0 as well, but same issue.

cody@fedora:~$ modinfo -p snd_hda_intel | grep power
power_save:Automatic power-saving timeout (in second, 0 = disable). (xint)
pm_blacklist:Enable power-management denylist (bint)
power_save_controller:Reset controller in power save mode. (bool)

I did notice that my pm_blacklist is bint instead of bool, not sure if that’s of any significance

6

It’s possible that the value cannot be changed at runtime (some drivers will require that they be completely unloaded and then that parameter be set by passing it at load time).

I’d also experiment with the other two settings. They are indicated to be booleans, meaning that they can be set to either 0 (off) or 1 (on).

Edit: It doesn’t look like the pm_blacklist setting would do anything useful: [RFC,v3] ALSA: hda: Add a power_save blacklist - Patchwork

7

bint is a superset of bool. In addition to 0 (off) and 1 (on), larger integral values can be set. You’d probably have to dig into the driver code to find out what the values greater than 1 mean though.

Correction: It appears that bint just a bool, but it always shows as an integer (0 or 1): moduleparam.h - include/linux/moduleparam.h - Linux source code v6.12.6 - Bootlin Elixir Cross Referencer

8

Seeing that the power_save kicks in after only 10 seconds, it is possible that your adjustment was made too late (since power save was activated before you made the change, the change seemed to have no effect).

I have the same laptop.
It seems like kernel 6.12 broke the audio, not to mention my entire system just got bricked a few minutes ago. I’m trying to roll back to 6.11, but it seems to be impossible.

For now the only way I can use my laptop is to switch to dGPU-only. But the audio is still broken, while with 6.11 I was able to fix it using sudo tee /etc/modprobe.d/snd-hda-intel.conf <<< "options snd_hda_intel power_save=0"

It should always be possible to install an older kernel. Generally, dnf --repo=fedora downgrade kernel* should work (and you will have to select the older kernel while booting or else make the older kernel the default[1]).

Thanks. I was trying to do it using Koji, since that was the only thing I could find in the docs.

Anyway, after the downgrade I ran sudo tee /etc/modprobe.d/snd-hda-intel.conf <<< "options snd_hda_intel power_save=0" since that config somehow got deleted after upgrading to F41. Audio is working again. The system is (I think) working fine too.

It’s interesting that cat /sys/module/snd_hda_intel/parameters/power_save gives you 10. On the 6.11 kernel (without the fix) it gave me 1. I made a post a few days ago about the same issue. Since then I also found out that Bluetooth audio is broken too. Something got seriously messed up in 6.12.

Same thing here, I have even dowgraded my kernel i use a dell latitude 7300,Nothing brings my sound back after the pop up saw an update from intel media driver for vaap don’t know if it will fix it ?

13

Ok so I found a solution! After reading through the referenced thread by @br0kenpixel I saw someone else had mentioned another thread, and someone there linked a solution that worked: https://github.com/DanielWeiner/tas2781-fix-16IRX8H/blob/main/README.md. And that’s my exact model of laptop (16IRX8H). So I ran the script, and it seems to be working great! It looks like it is indeed a couple of power-save issues causing the problem just as @glb had suspected. Thank you everyone, there’s no way I would have found this solution without your help.

That’s awesome!

By the way, I’m curious… Are you also getting a loud pop sound when rebooting? Does this fix remove it?

15

Yes I do still get a popping sound in the built-in laptop speakers when rebooting, even after applying the fix. It only happens during reboot and not during shutdown or regular startup. But it’s never been loud on my system, so it hasn’t ever bothered me. It almost reminds me of how it sounds when someone disconnects/reconnects an aux cable from an amp, except really quiet (at least on my laptop). The popping sound on reboot doesn’t seem to be happening through the headphones, only through the built-in speakers.
