checked the alsa-info.txt in #14, found the lifebook-extmic doesn't take effect, "model=liefbook-extmic" was added to kernel-4.19 but we are using kerel-4.15. So please test this dkms, if headset-mic still doesn't work, please generate an alsa-info.txt too.
thx. To install the dkms: sudo dpkg -i oem-audio-xxx.deb reboot to remove the dkms: sudo dpkg -P oem-audio-hda-daily-dkms reboot ** Attachment added: "oem-audio-hda-daily-dkms_0.1_all.deb" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1821269/+attachment/5266138/+files/oem-audio-hda-daily-dkms_0.1_all.deb -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1821269 Title: [Aspire ES1-131, Realtek ALC255, Mic, Internal] No autoswitch (4-pole combo jack mic doesn't detect) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1821269/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
