Kernel Regression between 5.4.0-26 and 5.4.0-40 causes laptop internal audio devices to fail to load w/o unacceptable workaround (Lenovo IdeaPad 5 15IIL05)

This change was made by a bot.

I have the same problem on a Lenovo Ideapad 5 (15IIL05), with Linux Mint 20 Xfce installed: sound works fully (incl. mic) on 5.4.0-26, but not at all on 5.4.0-40. For reference, I've had a discussion on the Mint forum: https://forums.linuxmint.com/viewtopic.php?f=49&t=323823

@Corbin, please remove the workaroud and regenerate the logs in the #1

@gogolink, please upload the logs as the #1.

thx.

Let us record a potential fix here:

    ASoC: SOF: Intel: drop HDA codec upon probe failure

    In case a HDA codec probe fails, do not raise error immediately,
    but instead remove the codec from bus->codec_mask and continue
    probe for other codecs.

    This allows for more robust behaviour in cases where one codec
    in the system is faulty. SOF driver load can still proceed with
    the codecs that can be probed successfully. Probe may still
    fail if suitable machine driver is not found, but in many
    cases the generic HDA machine driver can operate with a subset
    of codecs.

@Hui Wang: where can I find guidance on how to upload the logs? You need those 18 that Corbin posted in comment #1? Where would I find the scripts/commands that generate them?

Maybe it is: apport-collect 1886341

OK, think I got it. I'm adding apport file apport.linux.yukw0jij.apport as an attachment.
Keep in mind that after installing Mint 20 Xfce with kernel 5.4.0-26, and updating to 5.4.0-40.44, I did two things that changed what I get from the sound system, one for the better, the other for the worse (see forum discussion https://forums.linuxmint.com/viewtopic.php?f=49&t=323823):

sudo tee /etc/modprobe.d/alsa-fix.conf <<<'options snd-intel-dspcfg dsp_driver=1'

Here are the logs w/o workaround. Please let me know if you need anything else.

both machines are IdeaPad 5 Icelake platforms.

Could you please verify if 5.4.0-39 kernel has the problem or not?

sudo apt install linux-image-unsigned-5.4.0-39-generic linux-modules-extra-5.4.0-39-generic
reboot with the 5.4.0-39 kernel and upload the dmesg

To remove the 5.4.0-39 kernel
sudo apt -r linux-image-... linux-modules-extra-...

I did try 5.4.0-39 before, and it did have the same problem (= no sound). I also tried 5.4.0-37, and I think also 5.4.0-33. I'm a bit too tired now to install those kernels again and run dmesg, but can do it tomorrow, if it helps.

@gogolink,

If you have tried those kernels and those kernels still failed, there is no need to reinstall those kernels.

Your machine is ab Icelake machine and we hasn't had a chance to enable the sof audio on an icelake machine before. I have no idea why the hdmi codec init fails.

To debug this issue, we need to find the 1st workable kernel for this machine, for example, 5.7.0-rc1 not work, 5.7.0-rc2 work.

So could you please test the mainline kernel to find the 1st workable kernel like:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.6-rc3/
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.6-rc4/
...

I will do the same as well

@Hui Wang:
How do I actually load a mainline kernel?

I installed Ubuntu Mainline Kernel Installer, and used it too install kernel 5.6.3;
but at boot attempt, I get this message:

error: /boot/vmlinuz-5.6.3-050603-generic has invalid signature.
error: you need to load the kernel first.

@gogolink
try turning off secure boot

@Corbin
Thanks, that worked!

And with this I can report that sound in 5.6.3 DOES work for me. Will go back now and try to find the *1st* workable kernel.

Sound seems to be working fully on 5.6.0-050600rc3.
On 5.5.19-050519, sound was totally broken. When I clicked on volume control, the message was "not connected to the pulse audio server."

On 5.5.10, sound is also not working; but just as on 5.4.0-40, at least when I click on volume control (in panel), it does show me a volume level and allow me to open audio mixer, which shows "Dummy output" and "No cards available for configuration." (So there seems to be some change somewhere between 5.5.10 and 5.5.19, but the first workable kernel is 5.6.0.)

@Corbin and @gogolink,

On the 20.04, we could install the ubuntu 5.6.0-oem kernel, you could install that kernel on the 20.04. Let us see if that kernel has this issue or not.

Running now on 5.6.0-1010-oem, and sound is working! That includes the internal microphone.
Thank you, Hui Wang and Corbin!

The 5.6-0 OEM was the earliest version of the kernel I could get working as well.

Interestingly enough,this kernel seems to exhibit a seperate bug, but I will file that one seperatly.

Here are the apport logs.

Also the bug in question doesn't actually exist

@Corbin:
Hi Corbin, can I ask what that separate bug is? Since we seem to have the same kind of machine...

Well, previously on mint as well as the Ubuntu liveimage, fans would run at medium to high speed constantly despite running in gpu rendering mode and no visible cpu strain. The air coming out of the vents would be cold as well.

When i booted 5.6.0, the fans ran fast for a minute or so after boot, then everything returned to normal.

Like I said, it would merit a separate report.

I thought I noticed the same, so it wasn't just me. I installed TLP
looking at these pieces of advice:
https://itsfoss.com/reduce-overheating-laptops-linux/#comments
... and perhaps it's helped. Or it just settled to normal. Right now, fans
are reasonably calm.

We also want to fix this issue in the ubuntu 5.4 kernel, so I built a testing kernel, could you please test if that testing kernel work or not, if it doesn't work, please upload a complete dmesg.

thx.

Sound does *not* work for me on testing kernel 5.4.0-42
I'm attaching the dmseg output.

@Corbin,

You set "regression" in the bug title, suppose the audio in the 5.4.0-26 kernel works, what version of kernel is the 1st can't work -28, -33, -39 or -40? After I get the 1st failure kernel, I could check what patch introduced the regression.

thx.

@gogolink,

I built a new testing kernel, if you have time, please help test it. If it still can't work, we have to bisect if we want to fix it in the 5.4 kernel.

https://people.canonical.com/~hwang4/lp1886341/v2/

thx.

I will investigate when I have some time, hopefully later today.

@Hui Wang
The new testing kernel -- 5.4.0-42.46 -- does work on my machine! Sound
works, mic works. One odd thing: with headphones plugged in, sound is
output at both headphones and internal speakers. And it's not immediately
obvious to me how to mute the speakers but leave the headphones on.

Volume Control lists four output devices:

Smart Sound Technology Audio Controller HDMI3/DP3 Output
Smart Sound Technology Audio Controller HDMI2/DP2 Output
Smart Sound Technology Audio Controller HDMI1/DP1 Output
Smart Sound Technology Audio Controller Speaker + Headphones

I'm attaching dmesg output.

Actually, the use of built-in speaker and headphones at the same time happens only if I boot with headphones plugged in; and the way to mute the speakers but not the headphones is simply to unplug and reinsert the headphones. So that's fine. (It's different from what I'm used to, but acceptable behavior IMO).
And 5.6.0 is no different from the new testing kernel in that regard.

OK, thx. I will SRU the patches in the testing kernel first.

It actually didn't work for me, but that is likely because i did not load linux-modules-extra. THe download link for the deb keeps failing, but I'll try again tomorrow. So please disregard until then.

Yes, linux-module-extra is needed since all audio driver kernel modules are in this deb.

I am pleased to report your patched kernel works for me as well.

Excellent work!

Where can I check to see when this fix has been pushed out as part of an Ubuntu update?

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
