Here is another variant, now with RC6, works the sound and the nvidia drivers at the same time! (with some tricks):
A) FIRST TIME 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 p7zip- full 2) clone the kernel from github and checkout to v5.17 branch (Rather large, multiple GB's): * git clone https://github.com/torvalds/linux.git 3)Make a 7z of the linux folder in a clear state 7z a linux-clean.7z linux 3) get the patch and let it in one superior level of the linux folder: https://patchwork.kernel.org/project/linux- acpi/patch/20220121172431.6876-4-sbind...@opensource.cirrus.com/ A) FOR EACH RC RELEASE: 7z x linux-clean.7z cp Support-Spi-in-i2c-multi-instantiate-driver.patch linux/ cd linux git pull git checkout v5.17-rc6 git am Support-Spi-in-i2c-multi-instantiate-driver.patch make olddefconfig ./scripts/config --enable CONFIG_SERIAL_MULTI_INSTANTIATE ./scripts/config --enable CONFIG_SND_HDA_SCODEC_CS35L41_I2C ./scripts/config --enable CONFIG_SND_HDA_SCODEC_CS35L41_SPI ./scripts/config --disable CONFIG_DEBUG_INFO ./scripts/config --set-str CONFIG_SYSTEM_TRUSTED_KEYS "" ./scripts/config --set-str CONFIG_SYSTEM_REVOCATION_KEYS "" make -j 16 make modules_install make install The patch is mandatory to enable the sound in ubuntu, im tried without the path and the sound don't work. With this steps will do. In order to make work the nvidia drivers in the 17-rc6 im just change in "more drivers" option of ubuntu, the current versión of the nvidia driver for another (511 to 470 for example). Im using hybrid graphics mode in the bios. -- 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
