well finally found the way to make it work in the legion 7 2021 AMD (16achg6)...
this is a short tutorial to build the kernel with the patch (I've done it on fedora 35): 1) make sure you have all the tools to build the kernel (https://fedoraproject.org/wiki/Building_a_custom_kernel): * sudo dnf install fedpkg fedora-packager rpmdevtools ncurses-devel pesign grubby git 2) clone the kernel from github and checkout to v5.17 branch: * git clone https://github.com/torvalds/linux.git * cd linux * git checkout v5.17-rc4 * git pull 3) get the patch and install it: get the patch form this site: (top rigth corner "series" button): https://patchwork.kernel.org/project/linux-acpi/patch/20220121172431.6876-4-sbind...@opensource.cirrus.com/ * git am Support-Spi-in-i2c-multi-instantiate-driver.patch 4) load your old kernel config * make olddefconfig 5) change configuration at menuconfig as Howard Chu explained in his previous post * menuconfig -> Device Drivers / X86 Platform Specific Device Drivers / I2C and SPI multi instantiate pseudo device driver ------> Enable this 6) build the kernel * make -j 16 7) install the kernel * sudo make module_install * sudo make install 8) reboot and enjoy internal speakers (if anyone sees a mistake or something that I did wrong please feel free to correct these steps) Thank you to everyone who worked on this patch -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1958019 Title: [Lenovo Legion7 16ACHg6 82N6, Realtek ALC287, Speaker, Internal] No sound at all Status in sound-2.6 (alsa-kernel): Confirmed Status in alsa-driver package in Ubuntu: Confirmed Bug description: On my Lenovo Legion-7-16ACHg6 laptop I can't hear any sound by internal speakers, but it work by headphones connected to standard jack aux. uname -r 5.11.0-44-generic ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: alsa-base 1.0.25+dfsg-0ubuntu5 ProcVersionSignature: Ubuntu 5.11.0-44.48~20.04.2-generic 5.11.22 Uname: Linux 5.11.0-44-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.11-0ubuntu27.21 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC2: i3draven 1266 F.... pulseaudio /dev/snd/controlC0: i3draven 1266 F.... pulseaudio /dev/snd/controlC1: i3draven 1266 F.... pulseaudio /dev/snd/pcmC1D0p: i3draven 1266 F...m pulseaudio CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Sat Jan 15 15:10:53 2022 InstallationDate: Installed on 2021-10-11 (96 days ago) InstallationMedia: Ubuntu 20.04.3 LTS "Focal Fossa" - Release amd64 (20210819) PackageArchitecture: all SourcePackage: alsa-driver Symptom: audio Symptom_AlsaPlaybackTest: ALSA playback test through plughw:Generic failed Symptom_Card: Family 17h (Models 10h-1fh) HD Audio Controller - HD-Audio Generic Symptom_DevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC2: i3draven 1266 F.... pulseaudio /dev/snd/controlC0: i3draven 1266 F.... pulseaudio /dev/snd/controlC1: i3draven 1266 F.... pulseaudio /dev/snd/pcmC1D0p: i3draven 1266 F...m pulseaudio Symptom_Jack: Speaker, Internal Symptom_Type: No sound at all Title: [82N6, Realtek ALC287, Speaker, Internal] No sound at all UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 11/08/2021 dmi.bios.release: 1.49 dmi.bios.vendor: LENOVO dmi.bios.version: GKCN49WW dmi.board.asset.tag: NO Asset Tag dmi.board.name: LNVNB161216 dmi.board.vendor: LENOVO dmi.board.version: SDK0R32862 WIN dmi.chassis.asset.tag: NO Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Legion 7 16ACHg6 dmi.ec.firmware.release: 1.49 dmi.modalias: dmi:bvnLENOVO:bvrGKCN49WW:bd11/08/2021:br1.49:efr1.49:svnLENOVO:pn82N6:pvrLegion716ACHg6:skuLENOVO_MT_82N6_BU_idea_FM_Legion716ACHg6:rvnLENOVO:rnLNVNB161216:rvrSDK0R32862WIN:cvnLENOVO:ct10:cvrLegion716ACHg6: dmi.product.family: Legion 7 16ACHg6 dmi.product.name: 82N6 dmi.product.sku: LENOVO_MT_82N6_BU_idea_FM_Legion 7 16ACHg6 dmi.product.version: Legion 7 16ACHg6 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/sound-2.6/+bug/1958019/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
