Audio broken under Linux 5.4, dummy output [SOLVED]

Hello, the following logs are from a Lenovo X1 Carbon 7th gen laptop. After updating to Linux 5.4, the audio has stopped working.

Here is the journalctl log from 5.3, when audio worked.

Dec 02 14:13:58 kernel: Linux version 5.3.13-arch1-1 (linux@archlinux) (gcc version 9.2.0 (GCC)) #1 SMP PREEMPT Sun, 24 Nov 2019 10:15:50 +0000

And this is the journalctl log from 5.4, now that audio is broken.

Dec 03 11:16:37 kernel: Linux version 5.4.1-arch1-1 (linux@archlinux) (gcc version 9.2.0 (GCC)) #1 SMP PREEMPT Fri, 29 Nov 2019 13:37:24 +0000

I've also updated a Dell XPS 13 to Linux 5.4, but that laptop is running fine. The issue only happens on the X1 Carbon.

Looks like the firmware is not able to load. Is there anything I can do to help it load?

Re: Audio broken under Linux 5.4, dummy output [SOLVED]

Disabling SND_HDA_INTEL_DETECT_DMIC did in fact work! W00t!

I use systemd-boot. This is how I fixed it for my system.

First, I opened my default boot entry, /boot/loader/entries/arch.conf.

Then, I added the option to disable to the end of this line.

options cryptdevice=... root=... rw ignore_loglevel debug snd_hda_intel.dmic_detect=0

I rebooted and sound started working again!

Re: Audio broken under Linux 5.4, dummy output [SOLVED]

I've just got new HP Spectre x360 15-DF1033DX, installed Arch and got stuck with Audio. No output/input, no sound.

I used to change /etc/default/grub to have this line

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet splash acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012' snd_hda_intel.dmic_detect=0"

Then run in terminal

grub-mkconfig -o /boot/grub/grub.cfg

Then reboot.
Audio is now working on HP Spectre X360
Kernel 5.4.2
