@Dariusz, You said "The situation is different on impish - on this release the mic is available out of the box.". I remember the impish doesn't install firmware-sof-signed package out of box, so the the sof-cml.ri is still provided by linux-firmware of impish, and the sof-cml.ri in is impish is identical to the sof-cml.ri in the focal.
If so, I guess this is not an issue on the sof-firmware, maybe it is an issue on the kernel of 5.4.0. So could you confirm the mic could work under impish without the firmware-sof-signed package? And could you upload the complete dmesg under focal with the original sof-firmware in focal? About the bionic, I am afraid we couldn't make the mic work under it. To make the mic work, not only needs the kernel and sof-firmware, also needs to upgrade the alsa-lib, alsa-ucm-conf and pulseaudio. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1959681 Title: mic not working on HP-EliteBook-830-G7 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1959681/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
