The kernel 5.3.0-41 and 5.3.0-42 have some regression, please don't use them, we could wait for the -43 or just use -40.
>From the card long name you provided "LENOVO-20QD003JGE- ThinkPadX1Carbon7th-20QD003JGE", your machine is not covered by this SRU, that means the ucm doesn't work on your machine, so it is expected the internal mic doesn't work. I am preparing another SRU for alsa-lib, in that SRU I will hack the existing alsa-lib to let alsa-lib find the ucm based on the BIOS_Version instead of only based on the cardname/cardlongname. With that new SRU, for all X1C7 variants, we could use one ucm folder to support them. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1859754 Title: add ucm to make alsa/sof driver work under PA (variants of Lenovo X1 Carbon 7th, Dell cnl and cml machines) To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1859754/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
