A new element, I manage to get the sound back : killall pulseaudio pulseaudio -D
In fact, as I kill pulseaudio I have a very few time before the process being re-launched (I don't know why, I don't know by who). The sound works again only if pulseaudio is launched by me (as the current user) during this moment. A problem between pulseaudio and the sleep mode ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/315824 Title: Sound works for a while, then randomly stops working in 8.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/315824/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
