Had a similar problem with Lenovo S740 (Ubuntu 18.04, 19.10 and 20.04). Tried different combinations in alsa-base.conf, hda-jack-retask - nothing worked.
And then surprisingly this thread helped (see https://gist.github.com/hamidzr/dd81e429dc86f4327ded7a2030e7d7d9#gistcomment-3315737 ). What I've done is I appended next two lines to /etc/pulse/default.pa: # /etc/pulse/default.pa load-module module-alsa-sink device=hw:0,0 channels=2 # note that I used 2 here load-module module-alsa-source device=hw:0,6 channels=2 ``` For those of you having problems in Ubuntu 20.04 with Realtek ALC285 this could be a solution. ❯ uname -a Linux anton-Lenovo-Yoga-S740-14IIL 5.4.0-33-generic #37-Ubuntu SMP Thu May 21 12:53:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux Now internal microphone records audio, please try to see if it helps you -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1840725 Title: Microphone not working in Ubuntu 18.04.3 LTS on new hp- spectre-x360-convertible-15 laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1840725/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
