Thanks Hui, for the quick response. I've installed that package, and indeed, the microphone now works in apps like Audacity. Great.
However it still does not work in Chromium in Google Meet, the microphone appears as a device to use, but it shows as "disabled" and so when I unmute in Google Meet it then re-mutes after 2s. In syslog it shows still each time I unmute: Mar 21 18:57:22 user-ThinkPad-X1-Carbon-7th chromium_chromium.desktop[4806]: [4806:4806:0321/185722.248501:ERROR:pulse_util.cc(300)] pa_operation is nullptr. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1868330 Title: Lenovo ThinkPad-X1-Carbon-7th Gen microphone doesnt work Status in alsa-driver package in Ubuntu: New Bug description: On Focal Fossa the microphone is recognised but doesn't work.
