I got a similar problem: many "Bluetooth: hci0: last event is not cmd complete (0x0f)" in dmesg and the sound from the bluetooth speaker is distorted (but connected).
The problem goes away as soon as I close the "bluetooth setting" windows: basically the issue arises only while the controller is searching for new devices. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1748565 Title: Kernel regularly logs: Bluetooth: hci0: last event is not cmd complete (0x0f) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1748565/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
