I also have kind of that problem on Ubuntu 18.10. I don't want to have sound. So I mute every device. After a re boot the sound is turned back on again.
It's a laptop in a dock. The system detects multiple sound devices. Internal speakers and dock output. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1334329 Title: Sound input settings not saved To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1334329/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
