Lenovo Yoga 7 2-in-1 16AKP10 volume control bug
by Sandro Gähler 11 Jul '25

11 Jul '25

Hello I would like to report a bug for the brand new Lenovo Yoga 7 2-in-1 16AKP10. It has the same sound chip and also the same volume control bug as several older models. I thus assume that the same workaround, written by Philipp Jungkamp and later by Pascal Gross, will also work for this model. There are several lines with laptops that apply this workaround, for example this line in linux/sound/pci/hda/patch_realtek.c: SND_PCI_QUIRK(0x17aa, 0x3801, "Lenovo Yoga9 14IAP7", ALC287_FIXUP_YOGA9_14IAP7_BASS_SPK_PIN) Could you please add this line for my model? SND_PCI_QUIRK(0x????, 0x????, "Lenovo Yoga 7 2-in-1 16AKP10", ALC287_FIXUP_YOGA9_14IAP7_BASS_SPK_PIN), Please advise on how to determine the first two parameters. Thanks a lot for your great work and support. Best regards, --Sandro Gähler
