@ivandrs, Looks like the patch works as expected, the Bass spk is assigned to NID 0x17 with the patched kernel.
Now let us test the verbs. First, boot with the patched kernel, then run verbs in the #17, check if the bass spk works. If not work, please power off the machine then boot the machine with the patched kernel, then run the attached verbs (set-verbs-c930.sh, this verbs is composed according to hda-log-win.txt in the https://bugzilla.kernel.org/show_bug.cgi?id=205755) and check if the bass spk works or not. ** Bug watch added: Linux Kernel Bug Tracker #205755 https://bugzilla.kernel.org/show_bug.cgi?id=205755 ** Attachment added: "set-verb-c930.sh" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1926165/+attachment/5501304/+files/set-verb-c930.sh -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1926165 Title: Bass speakers not enabled on Lenovo Yoga 9i To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1926165/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
