I have the same audio card [8086:9d71] on Lenovo Yoga C930. Audio was working on Focal with 5.4 kernel with snd_hda_intel driver, but the microphone was not. I managed to get it working by following this guide: https://gist.github.com/crojewsk/4e6382bfb0dbfaaf60513174211f29cb
The biggest pain point for me is that Ubuntu kernels have CONFIG_SND_SOC_INTEL_SKYLAKE_HDAUDIO_CODEC disabled. So I installed `5.11.0-25-generic` HWE kernel sources, turned on that option, and rebuilt the kernel from sources. However, it is tedious to to that every time a kernel update is released. Is it possible to have that option turned on in Ubuntu kernel builds? Please let me know if I can help with testing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1915117 Title: [Regression] Audio card [8086:9d71] not detected after upgrade from linux 5.4 to 5.8 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1915117/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
