Canonical occasionally breaks sound compatibility between kernel release
(but I yet to figure out why). However, the XanMod kernel quite rarely
breaks Lenovo sound compatibility, thus I suggest you give that kernel a
whirl: https://xanmod.org/ (It's quite easy to install and remove if
needed).
I lost all sound devices recently using Kubuntu 22.04 and the 5.18
kernel on my Legion 7 16ACHg6. Following this guide restored my devices:
https://pipewire-debian.github.io/pipewire-debian/
Note: I installed all of the recommended wireplumber and BT options as
well as the pipewire packages.

Currently the 5.18-rc1 kernel throws an error when attempting install
510 drivers:
dpkg: error processing package nvidia-driver-510 (--configure):
dependency problems - leaving unconfigured
Subsequently, laptop refuses to boot discrete graphics when prime-select
= nvidia. However,
Ubuntu kernel 5.18v-rc1 includes the sound patches that fix sound for
LENOVO_MT_82N6_BU_idea_FM_Legion 7 16ACHg6 :
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.18-rc1/
Thank you everyone for all your efforts!

Great discovery on enabling the NVidia drivers under Ubuntu.
Hmmm, I too now cannot get past the "sudo make module_install" message:
No rule to make target 'modules_install'. Stop.
I tried re-installing headers and relinking build & src directories as
follows:
sudo ln -s /usr/src/linux-headers-`uname -r` /lib/modules/`uname -r`/build
sudo ln -s
*Ubuntu version:
1) install kernel build tools:
(https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel):
* sudo apt install libncurses-dev gawk flex bison openssl libssl-dev
dkms libelf-dev libudev-dev libpci-dev libiberty-dev autoconf git
2) clone the kernel from github and checkout to v5.17
Note to *Ubuntu users, every time I install a fresh, self compiled
kernel, the computer locks up on first boot. All subsequent boots work
fine.
