I now managed to install again nvidia drivers after I had the error that resembles to the one described here https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics- drivers-440/+bug/1878946
It might be that this sof-cfl.ri fixed this issue also. But maybe nvidia made a patch in the last 2 days. So the speakers and the mic work on 5.4.0-42-generic with the nvidia drivers also. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1892714 Title: Microphone not working on HP Omen 17 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1892714/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
