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.

** Description changed: + [Impact] + On the machine of Lenovo IdeaPad 5 15IIL05, the audio doesn't work, + checking the dmesg, I found the audio driver fails to initialize + because it fails on i915 audio codec probe. + + [Fix] + backport 3 patches from mainline kernel, move the i915 audio codec + init earlier. + + [Test Case] + Boot the kernel with these 3 patches, check dmesg, there is no + i915 audio codec probe error anymore, and audio driver initializes + successfully, and input and output audio devices all work. + + [Regression Risk] + Low, already tested these 3 patches on a couple of LENOVO dmic + machines (cnl and cml machines), all work as well as before. + + On Ubuntu 20.04, running kernel 5.4.0-40-generic, the internal speakers, headphone jack, and mic do not work at all. No audio devices appear in the Sound settings or in pavucontrol. By appending options snd_hda_intel dmic_detect=0 to /etc/modprobe.d/alsa-base.conf, I can get audio working, but the microphone (unsuprisingly) does not work. Appending options snd-intel-dspcfg dsp_driver=1 to alsa_base.conf as the same effect as dmic_detect=0. Attempts to fix with option snd_hda_intel device=generic or deveice=auto have had no effect. This bug does NOT manifest on 5.4.0-26-generic, the kernel version featured on the 20.04 live media. After installation, and updating to 5.4.0-40-generic, the bug manifests on the next boot. Note that the audio hardware seems to work properly w/o workaround on a small (< 5%) percentage of boots, but I have been unable to reproduce this.

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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886341 Title: 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) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1886341/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@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.

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.

Also the bug in question doesn't actually exist ** Description changed: On Ubuntu 20.04, running kernel 5.4.0-40-generic, the internal speakers, headphone jack, and mic do not work at all. No audio devices appear in the Sound settings or in pavucontrol. By appending options snd_hda_intel dmic_detect=0 to /etc/modprobe.d/alsa-base.conf, I can get audio working, but the microphone (unsuprisingly) does not work. Appending options snd-intel-dspcfg dsp_driver=1 to alsa_base.conf as the same effect as dmic_detect=0. Attempts to fix with option snd_hda_intel device=generic or deveice=auto have had no effect. This bug does NOT manifest on 5.4.0-26-generic, the kernel version featured on the 20.04 live media. After installation, and updating to 5.4.0-40-generic, the bug manifests on the next boot. Note that the audio hardware seems to work properly w/o workaround on a small (< 5%) percentage of boots, but I have been unable to reproduce this.

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."

@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.

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.
