Is https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1869481
possibly connected to this too?

Thanks for your answer. I am too hesitant to try -46 from bionic-proposed as
that requires updating ~30 other dependencies from -proposed.
I got the mic to work with upstream kernel 5.5.10, libasound2 1.1.3-5ubuntu0.5

Please try with 5.3.0-46, -42 and -45 has some problem.

Title:
[SRU] add ucm to make alsa/sof driver work
Hi, thanks for your work! I am having some trouble and would be grateful
for advice. I have a X1C7, running KDE neon (based on LTS 18.04). Two
days ago the package libasound2 was updated, which I suspect broke sound
& mic on my system. I had it working before on kernel 5.3.0.40 with some
solutions
Thank you for your reply and your work in general, Hui Wang! If any
testing is helpful let me know. I get the Product Name "20QES01L00" via

right? Does 1.1.9-0ubuntu1.2testucm already do this? (I had the led

I have a X1C7, Ubuntu 19.10 (Kernel 5.3.0-45), and only get a "dummy

only stereo) but no mic support. Also the mute LED does not work (but

some fixing patches are in the 5.3.0-43, but somehow they are not in the

kernel.
So please use -43 kernel or wait for -46 kernel.

I just see kernel 5.3.0-45-101 as a new kernel and in the changelog only
see "Bump ABI". Where can i see all changes and will it fix more of this
issue here or make it worse again?

Thanks so much for your help. It seems to work again now after adding
those options and switching the device once in pavucontrol. Really
appreciate your fast responses!

It is a kernel issue if your kernel is -42/-41, even you downgrade the
libasound, it will not help. either you install -43 kernel or you could
workaround it by adding "options snd-hda-intel dmic_detect=0" in the
/etc/modprobe.d/alsa-base.conf.

@Hui Wang
Thanks for the quick reply. If I understand correctly, 5.3.0-43 is not
yet in the bionic repository, but in bionic-proposed. I'm a bit hesitant
to install this after having just gotten the system back to boot again.
Is it intentional that there is this incompatibility but libasound is
@Ingo,
According to the kernel log you posted, I guess you install the
5.3.0-42/41 kernel, please try with 5.3.0-43 kernel.

Thanks for the explanations. I'll keep working with pulseaudio+ucm for
now so as to be able to test your fixes. If it becomes too unbearable
I'll revert to dmic_detect=0

@Jean,
You mentioned Bluetooth audio, that remind me that the testing alsa-lib
in the #66 has some problem, I just fixed it and uploaded a new version
to it, please try it. And testing alsa-lib is not SRUed yet, I plan to
SRU it with this bug: #1868210.
And Because the pulseaudio+ucm works
I encounter a few other issues which appeared since I upgraded to this
setup when using a secondary screen over HDMI and a bose QCII bluetooth
headset.
