A note on the 'model' and 'patch' options of of the 'snd_hda_intel' module.
The 'model' option can be used to apply a fixup written for another device. You can check the fixups available for the ALC287 in the docs or in the 'alc269_fixup_models' array at sound/pci/hda/pathch_realtek.c:9551. See https://www.kernel.org/doc/html/latest/sound/hd-audio/notes.html#model-option The 'patch' option is similar, but way more powerful. I used it to try a lot of configurations before I got the sound working. See https://www.kernel.org/doc/html/latest/sound/hd-audio/notes.html#early-patching I'd like to see the patch merged so people with devices for which the fixup might work can try the module option instead of compiling a patched kernel. Something along the lines of --- # /etc/modprobe.d/snd.conf # use snd_hda_intel instead of snd_sof options snd_intel_dspcfg dsp_driver=1 # enable the fixup options snd_hda_intel model=alc287-yoga9-bass-spk-pin --- should then work to apply the fixup until a PCI_QUIRK is added. I'll give an update when I know when it's going mainline. There were actually three problems with the bass speakers on the Lenovo Yoga9 14IAP7: 1. The Pin Complex node of the codec with NID 0x17 on which the bass speakers are connected reported itself as unconnected. 2. The bass speakers have amplifiers which need to be enabled via NID 0x20 of the codec. (similar to the Lenovo Yoga 7 14ITL5 fixup) 3. The driver connected the bass speaker Pin Complex to the DAC on NID 0x06 of the codec which has no volume control. (bass speakers always on max volume) You can check whether your device is affected by problem 1 by checking the 'Pin Default' on 'Node 0x17' in the 'HDA-Intel Codec information' in your alsa-info.txt. e.g. $ grep -A6 'Node 0x17' < alsa-info.txt A 'Pin Default' that starts with 0x4, 0x5, 0x6 or 0x7 indicates and unconnected pin and thus problem 1 assuming the bass speakers are really on NID 0x17 on your device. If your device is not affected by problem 1, the mainline fixes for the 'Yoga 7 ITL5' or 'Legion 7i' might already work. -- 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
