I've managed to get my Lenovo Legion 7 16ACHg6 speakers working on kernel 5.18.x by setting the following kernel configuration
CONFIG_SND_SOC_CS35L41_I2C=m CONFIG_SERIAL_MULTI_INSTANTIATE=m However, kernel 5.19.x seems to break it as with the same kernel config, the modules are loaded by do not work. Apart from the speaker, I'm having the same issue with the touchpad (works on 5.18, but not on 5.19). Any ideas why it would work on 5.18, but not on 5.19? -- 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
