With last update the sound started working, but it is too loud and distorted. Volume regulation doesn't influence it at all, except of 0 value.
We have had some issues with ALSA UCM profiles for Bay and Cherry Trail based devices, which were fixed in recent updates. Can you please try the following: 1. Save all your works and close all your apps 2. From a terminal run the following 2 commands: sudo rm /var/lib/alsa/asound.state sudo reboot --force This will reset your (possibly bad) mixer settings from the previous issues and will hopefully fix this.
Thank you, Hans, for your proposal. Anyway, as it could be solution on Lenovo Miix 320, it doesn't change anything on Lenovo Miix 2 10 and the issue persists.
Ok, can you please do: dmesg > dmesg And attach the generated dmesg file here? And also please run: alsa-info.sh And attach the file it generates here.

I have reproduced this problem on a Lenovo Thinkpad8 devices which also uses the cht-bsw-rt5672 machine driver. This is a problem with the recent conversion of the UCM profiles to the UCM2 format. I've prepared a patch fixing this and I have just submitted this upstream. Jaroslav, the alsa-ucm-conf patch-series which I just send out also contains some other bug-fixes, any chance we can get an update Fedora package with these fixes?

The sound started working without any noise, but it is very silent. The maximum 100% corresponds to 50% of volume level. It should be rescalled.
I noticed it is only working from small built-in speaker, not from main speakers at the keyboard. There is still the same defect of loudy noice as before. And what neither works are volume buttons on the corner of tablet.

So I did some googling and it seems that there are extra speakers inside the keyboard-dock. That is a somewhat exotic solution. I'm afraid I cannot really help with surporting that until I manage to get my hands on one of these devices myself. I will keep a look out for one of these devices on the second-hand market.

I've managed to get my hands on one of these devices; and although it was quite a bit of work to get to the bottom of this, I've figured out how the extra speakers work and wrote a kernel patch fixing this. I've submitted the patch upstream and it is on its way to be included as a fix for the 5.8-rc# kernels: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git/commit/?h=for-5.8&id=0ceb8a36d023d4bb4ffca3474a452fb1dfaa0ef2 5152 are you still trying to use this tablet + dock with Fedora? If so then let me know, then I will submit a merge-req to add the patch to the Fedora 5.7 kernels which should hit updates-testing soon.
Thanks for solving that issue. The problem persists on external speakers when I start Fedora with Kernels 5.6.16 or 5.7.8, while with Kernel 5.8.6 the sound is understandable. It only has lower quality than on Windows, but sound control works.
