Seems you haven't installed the kernel source tree. Obtain the kernel headers and the compiler, and download the kernel sources ... sudo apt-get source linux-image-$(uname -r) sudo apt-get build-dep linux-image-$(uname -r) For compiling a kernel module that's a good doc. Start with: https://yoursunny.com/t/2018/one-kernel-module/ ... at the end there's only the need to replace one kernel module Seems that your ALC287 has the id 0x17aa3847 Unfortunately having never done that before will need some learning time ... The 2nd method would be to use the applyverbs method used also in one of our early trials (see comment 403). Please make sure that the underlying "hda-verb" is installed, which may need some searching. It simple fires the needed sequence to the devices as done in the kernel patch. Good luck ... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1958019 Title: [Lenovo Legion7 16ACHg6 82N6, Realtek ALC287, Speaker, Internal] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/sound-2.6/+bug/1958019/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
