I also have this problem. Mostly I have Rhythmbox running (or at least it's started but doesn't play). Today it also happened with Audacious player. I can't reproduce it with the steps provided above. It also doesn't happen every time I receive a new email, but pretty often (maybe at least once a day, sometimes more often, maybe depending on email traffic).
I also suggest to change the title of the bug into a more meaningful title: "Thunderbird freezes when playing notification sound for new email" -- sound in thunderbird https://bugs.launchpad.net/bugs/194573 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
