@githubee thank you for posting this, looking forward to the next kernel update

> seems to work with kernel 5.13 on ubuntu 21.10. same experience as yours, the back arent loud at all. i thought kernel 5.18 would fix the issue according to...

I have tried the new Ubuntu 22.10 today to check if Pipewire fixed anything. No luck, the subwoofers do not wotk still.

Unfortunately no updates so far. You can check the related links, kernel issue reports: https://github.com/milkovsky/Linux-on-Lenovo-Slim-7-Carbon-AMD#speakers

Short update: The issue is still present in Pop!_OS 22.04 LTS, 6.2.6-76060206-generic

@tirithen you are absolutely right. We need to figure out how to patch the `patch_realtek.c` with the right values. Unfortunately I do not have an appropriate experience/knowledge for this. Here...

Nice research! Thanks for sharing. We could also ask the others community on how did they make the fixups for the other laptops with Realtek.

@AlexMV12 thank you for reporting, could you please name your distribution, kernel?

@AlexMV12 thanks, good to hear! Suspend works stable for me in ubuntu 22.04 LTS (5.15.0-25-generic). In supendend mode the laptop lost ~10% battery in 1,5 days.
