I can also confirm this for 16.04. I note a very similar error in the syslog:
May 28 17:34:58 afforess-pc pulseaudio[2004]: [pulseaudio] module-bluez5-device.c: Default profile not connected, selecting off profile May 28 17:35:00 afforess-pc bluetoothd[1009]: /org/bluez/hci0/dev_20_9B_A5_5D_BB_30/fd2: fd(31) ready May 28 17:35:00 afforess-pc pulseaudio[2004]: [pulseaudio] bluez5-util.c: Transport TryAcquire() failed for transport /org/bluez/hci0/dev_20_9B_A5_5D_BB_30/fd2 (Operation Not Authorized) May 28 17:35:00 afforess-pc kernel: [91164.555960] input: 20:9B:A5:5D:BB:30 as /devices/virtual/input/input27 I did some digging at one point, and the error from bluez5 seems to originate from DBus, and may be a permissions issue with the bluetooth DBus configuration or pulseaudio DBus configuration. The workaround suggested by Con Kolivas works, but is very annoying. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577197 Title: Pulseaudio bluez5-util.c: TryAcquire() failed - Operation Not Authorized To manage notifications about this bug go to: https://bugs.launchpad.net/bluez/+bug/1577197/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
