Now something intriguing: part of the solution was blacklisting the acer_wmi module so that
$ lsmod | grep acer_wmi returns nothing. If I turn my Bluetooth on, pair to my headset, start playing a song and then $ sudo modprobe acer_wmi immediately the sound starts to come out through my laptop's built-in sound boxes. $ lsusb Bus 001 Device 002: ID 8087:8001 Intel Corp.

Shouldn't that be reported to the upstream kernel maintainers? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1597961 Title: [Acer Aspire E5-573] Qualcomm Atheros Bluetooth 4.0 not working on [Ubuntu 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1597961/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
