Hello everybody I've seen that there's a module in the new Kernel-RC for bass speaker problems with new Lenovo (written by Philipp Jungkamp): SND_PCI_QUIRK(0x17aa, 0x3801, "Lenovo Yoga9 14IAP7", ALC287_FIXUP_YOGA9_14IAP7_BASS_SPK_PIN) Could you please add the exact same line for a similar model with the same Problem? SND_PCI_QUIRK(0x17aa, 0x3869, "Lenovo Yoga7 14IAL7", ALC287_FIXUP_YOGA7_14IAL7_BASS_SPK_PIN) I'm neither a developer nor a coder so I don't know how to contribute to the Kernel, I just played around with Philipps patch, changed the lines according to my model and it works now. I would really appreciate your help and of course, if you have any questions feel free to contact me. Thanks in advance, Pascal
