Hello,

I've been trying to figure out why I've been getting these errors and if these errors can be ignored? When I run journalctl -a -p err I see the following errors:

Jul 05 08:20:31 fedora kernel: snd_hda_intel 0000:01:00.1: spurious response 0x0:0x0, last cmd=0x4f0015

Jul 05 08:21:14 fedora systemd[1735]: Failed to start Application launched by gnome-session-binary.


I've googled and cant find much. I can say that the sound works with no issues, using both my speakers and my wireless logitech headphones. But I am not really sure why I am seeing this. Is this a driver issue?

Any help would be greatly appreciated!
 


People definitely need to learn how to use code tags; they make code output more readable:

There seems to be something wrong with snd_hda_intel audio driver. Are you having issues with your audio system? What were you doing before getting these errors?

Good point about the code tags, I will make sure to do this going forward!

In terms of audio, everything works well. I tested both my speakers which are connected to the motherboard integrated sound card. I also tested with my wireless headset that uses a dongle in a USB slot, and that works well too. I can switch between headphones and motherboard audio without any issues.

Really strange. When I Google this error, people are saying the sound does not work for them, but that is not the case for me.

Maybe you should ask at the Fedora forums https://ask.fedoraproject.org/ and have better luck finding an answer for that. Forum's moderators @KGIII or @wizardfromoz could also move the thread to the Fedora one, so fedora users can give an advice too.

then paste the terminal/commands' output in between the tags. :)
 
If your audio is working as expected I wouldn't worry about it.

Looking at the error messages, it's mentioning a specific line in a c code source file and the error I would think it's doing certain checks in the program and because they are non-fatal errors it's just reporting back errors where it's not finding what it's looking for. So I would think those are optional what it's checking for because if those were mandatory it would probably give back a fatal or something like that and your sound wouldn't be working.

Thanks! I will check out Fedora forums in the future as well, there might be someone there who've gone through this before on Fedora.

p.s code inserts seem quite simple :cool:

Thanks! I figured it might not be a big deal since the sound is working, but as I was not 100% sure, I figured I'd ask.
 
Hang on to your hat, Prof, I'll move this to Fedora subforum.

What version of Fedora?
Fedora34 uses pipewire instead of PulseAudio (or Jack).

alsactl is gone now (I think you can manually install it).
But it's interesting there are still any applications trying to use it.

Yep, Fedora 34. Thanks for the info, I did not know about alsactl :)
 
I'm having this same issue on my Fedora 34 machine ever since I shifted from Ubuntu. I wonder why I get this error. And if there is a workaround/fix to solve this issue.

@TheProf Can you share the link if this same issue is posted over askfedora community?
 
Looking at the logs and poking around in the code. It seems to me that the ALSA sound doesn't support UCM (Use Case Manager) for this particular audio chipset. That seems assinie given we are talking about Intel HDA audio which is a standard chipset. (unless it's some weird offshoot the normal Intel HDA audio chipset)

That said, I did find where someone dropping back to an LTS kernel resolved the error. This could mean that a kernel was released that has a bug in it as it pertains to this chipset.

Does this mean is there a fix for this issue in 5.14 or 5.15? Or just opposite of fix, a problem?

I never fixed it on my end. I also didn’t have any issues with my sound so I just left it as is. Eventually I switched to Manjaro and don’t have that issue any more.
