For 18.04 and 19.10, the alsa-lib only supports ucm, Intel audio team write the ucm confs and this is sth I plan to SRU to Eoan and Bionic in this bug.
For 20.04, we choose alsa-lib-1.2.1.2, it supports ucm2, and upstream writes the ucm2 confs based on the Intel audio team's work, we use #1862505 to track it. So the ucm for bionic and eoan is not backported from ucm2 of 1.2.1.2, it is maintained by Intel: https://github.com/thesofproject/alsa-ucm- conf.git the ucm2 for focal is maintained by upstream: https://github.com/alsa- project/alsa-ucm-conf.git, it is written based on the Intel's work. -- 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/ubuntu/+source/alsa-lib/+bug/1859754/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
