** Description changed: + Impact: + + A patch we carry for Ubuntu touch introduced a change that originally + was required to make sure PulseAudio did not crash. This patch was + ported to PulseAudio 8 in Xenial, but the patch author's bluetooth + hardware that was to hand at the time worked so was assumed to be ok. + However, the opposite is now happening, i.e PulseAudio is crashing with + a subset of Bluetooth hardware. + + Regression potential: + + Very low to none. As can be read in this report, much debugging and + testing has been done to find the problem, and the eventual fix. + Moreover the change is the removal of a patch hunk that removed a line + of code originally present in PulseAudio. + + Test case: + + NOTE that this test case applies to bluetooth hardware that is + identified as not working in this bug report. + + 1. Install, or upgrade to Xenial or yakkety. + 2. Pair your bluetooth device in the bluetooth settings in the relevant settings application for your desktop environment. + 3. Once paired, you will notice that sound stops working, as pulseaudio has thrown an assertion error. + 4. You do not have to remove your audio device from the paired device list, but it may be easier to do so for the next part of the testing. + 5. Update to the version of PulseAudio in xenial-proposed which is 1:8.0-0ubuntu3.1, or in yakkety-proposed, which is 1:9.0-2ubuntu2.1. + 6. Re-pair your device. Audio should continue to work, and you should be able to switch to your bluetooth device and use it. + + + Original bug report: + 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. This did not happen on Ubuntu 15.10 (which was an upgrade of 15.04).
