After reboot a few times, the sound card started to work But rebooting again, the problem came back.
I tried reboots, and turning off then on. Sometimes, it works. Sometimes it does not. Could be related to the initialization of the sound card Or when the system is rebooted or turned off and something is sent to sound card Maybe one of those two parts have been changed in that kernel version ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1894881 Title: [XPS 13 9300, Realtek ALC289, Speaker, Internal] Pulseaudio fails to detect card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1894881/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
