@pirr, Can you copy sof-dyndbg.conf.txt as |
|
@pirr Are you saying kernel 6.11.3.arch1-1 + sof-firmware 2024.09-1 works, and kernel 6.6.56-1-lts + sof-firmware 2024.06-1 also works, but kernel 6.6.56-1-lts + sof-firmware 2024.09-1 doesn't work? |

I think it is the introduction of tdfb with Enum controls in sof 2024.09-1. The 6.6.y stable does not have support for enum type. @singalsu, @kv2019i, I can try to see if it can be backported, but it is a feature, not a bug fix - but since the mix of new and old topology is a possibility, it can be viewed as bug fix. @pirr, I think for MTL you should not use 6.6.y LTS kernel - the force_probe for MTL i915 support got dropped with 6.7 kernel for example, so the odds that the 6.6 LTS is not working is high. To note: the enum control support is also added with 6.7 kernel, I think that should be the baseline for MTL. |
|
Update: with these patches picked to stable 6.6.y, there is no longer NULL dereference: |
|
@pirr, you need to use force_probe to get display working with the 6.6 LTS kernel? I cannot see that patch to be backported, for MTL 6.6 kernel is just too old to be used. |
|
@bardliao yes it is. Yesterday I updated to 6.6.57-1-lts, but the error remained. @ujfalus
I use 6.6 LTS because on 6.11 speakers volume cannot be changed (only mute or at full volume). And yesterday working on kernel 6.11 I encountered that the laptop freezes. I don't know the reason yet, but I've seen errors that are related to sof. Here is log
I didn't change anything in the kernel. But apparently that's how it is. |
|
@pirr, I think your issue is identical to thesofproject/sof#9572 with 6.11 kernel regarding to the kernel errors. The speaker volume control worked with 6.10 kernel or with older sof-firmware package? Have you tried with GUI or did you checked also with Can you file an issue for it (volume control not working)? |
|
Moving the issue under kernel. |
For this I use buttons on my laptop. They change the Speaker (on picture) in alsamixer. For kernel 6.6 I use Alsamixer
Should I file a new issue in sof project? |
Lets start with a sof linux issue and we can move it to the firmware based on the logs |

@pirr, I have sent the backports but they have not yet taken, I think the issue can closed, thank you for the report! |

Describe the bug
I am dealing with a NULL pointer dereference after updating from
sof-firmware 2024.06-1tosof-firmware 2024.09-1on EndeavourOS (ArchLinux). The sound doesn't work at all. I tried it on 6.11.3.arch1-1 and there were no problems there (I just can't adjust the volume, but I had this problem before too).I tried:
As write there https://thesofproject.github.io/latest/getting_started/intel_debug/introduction.html#pci-devices-introduced-after-2016
I used
options snd-intel-dspcfg dsp_driver=1and the sound worked (can't adjust the volume).System

To Reproduce
I suppose this can be reproduced on a laptop with a sound card like mine (Intel Meteor Lake-P HD Audio vendor: Lenovo) on kernel 6.6.56-1-lts arch: x86_64 bits: 64 compiler: gcc v: 14.2.1.
Reproduction Rate
100%
Expected behavior
The sound works and there are no errors related to sof.
Impact
The Sound device doesn't work.
