This issue persists even after the latest (March 2020) BIOS update from Lenovo. I posted about this here on the Lenovo forums:
https://forums.lenovo.com/t5/Lenovo-Yoga-Series-Notebooks/After-latest- BIOS-update-audio-not-working-on-Yoga-C930/m-p/5009564 Is our only hope getting the Lenovo BIOS devs to release a fix? Can we fix this in the BIOS ourselves? I rate the probability of ever hearing from Lenovo about this at around 0%. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1845797 Title: Microphone not detected Lenovo Yoga S940 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1845797/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
