Ok, as suggested by Simon, I've added some extra debugging to PulseAudio, with the Ubuntu Touch patches re-enabled. At the time of writing, this has just been pushed to my personal package archive for Xenial.
If folks experiencing this problem could install the version of PulseAudio from my PPA, and get a log as outlined at https://wiki.ubuntu.com/PulseAudio/Log that would be great.I suggest starting pulseaudio, then turning on your bluetooth device. Attached is my own log, for reference. ** Attachment added: "pulse.log" https://bugs.launchpad.net/bugs/1574324/+attachment/4748670/+files/pulse.log -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1574324 Title: pulseaudio crashes when connecting to bluetooth headphones (due to ubuntu changes?) Status in pulseaudio package in Ubuntu: In Progress Bug description: When I attempt to connect my Jaybird Bluebuds X to Ubuntu 16.04 pulseaudio crashes, this does *NOT* happen with a Jambox which leads me to believe it's an intermittent problem with some hardware.
