The issue has never been predictable (at least not to me) and I still had 2 failures with -proposed. If flaws in my testing can be found - please notify me. My 'primary' box has 19.10 on it, thus the use of d780. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1816394 Title: Ubuntu 19.04/19.10 qa:test - suspended system resumed without audio (fixed with pavucontrol toggle) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1816394/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
