Hello everybody,
I noticed I don’t have sound on my laptop. Even worse, I have no audio device to select in Gnome Settings > Audio, Evolution hangs when a mail arrives (the biggest issue), YouTube videos don’t start playing (i.e. Vivaldi hangs and taints the kernel, or something along those lines)
I’m running up-to-date Manjaro Gnome on Lenovo X1 Carbon, which has Intel Tiger Lake audio device:
> sudo lspci -s "00:1f.3" -v
00:1f.3 Audio device: Intel Corporation Tiger Lake-LP Smart Sound Technology Audio Controller (rev 20) (prog-if 80)

Kernel driver in use: sof-audio-pci-intel-tgl
Kernel modules: snd_hda_intel, snd_sof_pci_intel_tgl
According to a quick dmesg, the firmware and kernel modules seem to load fine (abeit the firmware seems to be on newer ABI?):

heinä 18 09:52:06 carbon-x1 pipewire[2119]: ALSA lib parser.c:1194:(parse_sequence) error: sequence command 'devdisall' is ignored
With that as the lead, I found that ALSA 1.2.7.2 fixed a typo from ‘devdisall’ to ‘disdevall’. Sure enough, I have 1.2.7.1 installed:
> pacman -Qs alsa-ucm-conf
local/alsa-ucm-conf 1.2.7.1-1
ALSA Use Case Manager configuration (and topologies)
Any ideas how to tackle this? Can it really be the ignored sequence command that borks the whole pipewire?
