Testing 6.11.0 - No audio

Testing 6.11.0 - No audio

[Manuel Quintero F]

Hi, I compiled the mainline kernel 6.11.0, as a result the audio does
not work, I don't know if it is a kernel error. Looking at the dmesg I
notice the following:

[    0.461474] Loaded X.509 cert 'wens:
61c038651aabdcf94bd0ac7ff06c7248db18c600'
[    0.461482] ALSA device list:
[    0.461483]   No soundcards found.
[    0.461769] cfg80211: loaded regulatory.db is malformed or
signature is missing/invalid
[    0.473025] snd_hda_intel 0000:00:1f.3: Cannot probe codecs, giving up

I share the complete dmesg:

Looks like you don't have any sound devices :)

Try using 'git bisect' to find the offending commit and let the
developers on the linux sound mailing list know what happened.

good luck!

Hi Greg, the same thing happens with 6.10.11.
Note: works fine with the latest debian testing kernel.

Re: Testing 6.11.0 - No audio

[Manuel Quintero F]

I compiled version 6.10.9, which is the debian kernel version, to see
if it worked, but it gave me the same audio problem.

Is there something in debian kernel 6.10.9 that makes the audio work?
What could it be?

Odds are that kernel has a driver built into it that your kernel config
that you used to build your custom kernel does not.  Make sure the
configurations match properly and see if that solves the issue.

good luck!

Did you use the config file from Debian to build your kernel?

Are the loaded modules are the same between the two?

I admit, I don't have a lot of context here, but I'd suggest, If it
works with the Debian testing kernel:
* check out the same vanilla / baseline version as that - 6.10.9, I
think you said
* get the config from the Debian kernel. Boot to it:
sudo modprobe configs
gzip -d < /proc/config.gz > .config
* there could be different options included in the Debian patches, so:
make olddefconfig # use defaults
* build and try that kernel, and let us know if it works

Re: Testing 6.11.0 - No audio

[Manuel Quintero F]

I already have audio with the compiled kernel. I copied the
configuration /boot/config-6.10.9-amd64

I had to do it by hand, copy it and rename it to .config because the
command shown in https://kernelnewbies.org/KernelBuild, does not work:

cp /boot/config-`uname -r`* .config

it shows me the error that the ".config" directory does not exist.

with this the audio works now.

Note: Note that I install many modules, I think I install them all, it
takes a long time.

Thanks to everyone for your answers.

How can I continue doing deeper tests in the kernel? :D

I'm willing to bet that you have a /boot/config-6.10.9-amd64 and also a
/boot/config-6.10.9-i686  or similar, so when you did the cp command, the *
expanded to 2 filenames.  And if there's 3 or more filenames total, the last one needs
to be the target directory to copy the 2+ preceding files into.

Moral of the story - beware of shell metacharacter expansions.
If you're unsure of what's going on, try sticking an 'echo' in front
of the command:

$ echo cp /boot/config-`uname -r`* .config

Having said that, I'm not sure what changes to make to the webpage to
avoid this issue....

As you have found out, defconfig works for almost no one, please don't
do that.  There's lots of documentation out there for building a new
kernel image, I suggest using the one on the kernelnewbies.org site,
that will help solve this type of issue.

Re: Testing 6.11.0 - No audio

[Aruna Hewapathirane]

[-- Attachment #1.1: Type: text/plain, Size: 2408 bytes --]

It looks like there are a few potential issues contributing to the sound
problem:

   1.

   *ALSA not detecting sound cards*:
   The message [ 0.461483] No soundcards found indicates that ALSA
   (Advanced Linux Sound Architecture) didn't detect any sound devices. This
   might be due to a missing or incompatible kernel module or driver.
   2.

   *snd_hda_intel codec probe failure*:
   The line [ 0.473025] snd_hda_intel 0000:00:1f.3: Cannot probe codecs,
   giving up suggests that the Intel HD Audio driver (snd_hda_intel) is
   unable to properly communicate with the audio codecs. This could be due to
   missing firmware, an incorrect configuration, or a regression in the kernel.
   3.

   *Malformed or invalid regulatory database*:
   The message [ 0.461769] cfg80211: loaded regulatory.db is malformed or
   signature is missing/invalid indicates that the wireless regulatory
   database is malformed or invalid. While this affects Wi-Fi, it could
   indirectly affect audio if there’s an interaction between the kernel
   modules (such as shared interrupts). This might need fixing too.

Run: *ls /boot/config-*.**  it will show you a list of all config files you
have. I would roll things back to a config where you know for a fact sound
worked. Then once I have the sound back up and working I would use 'this
sound is working config' and copy it over to build the new kernel ensuring
sound will be there.

You can also try: *sudo modprobe snd_hda_intel*

Happy troubleshooting :-)

Hi Manuel, once you get the kernel working the way you want you may want to
explore 'make localmodconfig'

This is particularly useful when you:

   - Want to reduce the kernel size by stripping out unused modules and
   drivers.
   - Need a kernel tailored for specific hardware.
   - Are recompiling a kernel for embedded systems or custom environments.
