Please try some newer (or older) kernels from: https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D and tell us which versions, if any, avoid the bug. ** Also affects: pulseaudio (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Changed in: bluez (Ubuntu) Status: New => Incomplete ** Changed in: linux (Ubuntu) Status: New => Incomplete ** Changed in: pulseaudio (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1838180 Title: apps use speakers when bluetooth headset is active (REGRESSION) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1838180/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
