@Paolo, So far, both ucm2 from upstream and ucm from Intel only support 2 speakers, for Bass speakers support, the upstream is discussing it, please read this thread: https://mailman.alsa-project.org/pipermail /alsa-devel/2020-February/162701.html, if you have some idea, please reply that thread.
And after the Bass speakers support is ready, I will co-work with Intel audio team to backport it to ucm. (maybe need some change in the pulseaudio too.) -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
