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 5.4.0-23-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. With the workaround enabled, inxi -A gives

description |
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. With the workaround enabled, inxi -A gives

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. With the workaround enabled, inxi -A gives

[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. With the workaround enabled, inxi -A gives
