This bug was fixed in the package alsa-lib - 1.1.3-5ubuntu0.5 --- alsa-lib (1.1.3-5ubuntu0.5) bionic; urgency=medium * d/p/0020-add-bios-version-for-looking-for-ucm.patch Add a new way to looking for the ucm by DMI bios_version. Without this patch, the alsa-lib looks for the ucm by cardlongname first, if it fails, then by the cardname. This has a problem at least on LENOVO machines, since a LENOVO model has the same audio design but it has hundreds of cardlongname, we need to create hundreds of folders for one model, that is unacceptable. LENOVO told us a LENOVO model has the unique biso_version, we could use it to find the ucm. After applying this patch, the alsa-lib looks for the ucm by cardlongname first, if it fails, it will use bios_version, if it also fails, it will fallback to cardname.

I'm running the proposed version on eoan, lenovo X1C7. Can confirm the microphone works. Two questions: 1) What is the new 'configuration' dropdown in the settings->Sound It has the options 'Play HiFi Music', Play to Hdmi1...3' 2) My Output device was selected as the speakers on the laptop. However sound was played over my external monitor. After switching to the external monitors and switching back the sound was on the laptop speakers. And then the microphone started working.
