This issue persists for me, on a C930 with 5.4.21. Adding `snd_hda_intel.dmic_detect=0` has no effect for me: there is sound, but only from the two front speakers. The rest of the speakers don't work.
Here's my alsa info, if it helps: http://alsa- project.org/db/?f=ab906a5a6eeeddc4926a6ad543c2d42d7a21ecdf Let me know if there's a way I can help debug this. -- 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
