For pulseaudio changes, I got this changelog:

pulseaudio (1:8.0-0ubuntu3.3) xenial; urgency=medium

  [Luke Yelavich, Konrad Zapałowicz]
  * Fixed multiple interrelated problems with using Bluetooth audio (A2DP),
    where users would experience some combination of:
    - Bluetooth headset/speakers listed but not selectable in Sound settings
      (LP: #1283003)
    - [regression] Bluetooth audio no longer supports A2DP (stuck in HSP/HFP
      mode) (LP: #1438510)
    - [xenial] Bluetooth device doesn't play any sound in A2DP mode unless set
      to HSP/HFP first (LP: #1582213)
  * Specific patches from upstream used to address the above problems:
    - 0103-bluetooth-Add-support-for-automatic-switch-between-h.patch
    - 0104-bluetooth-Add-support-for-automatic-switch-bluez5.patch
    - 0106-bluetooth-Add-optional-heuristic-for-switching-betwe.patch
      . Backport from upstream to fix a bug in Xenial where an incorrect
        audio profile is applied for a headset connected over Bluetooth
        making using it impossible.
    - 0105-bluetooth-policy-do-A2DP-profile-restoring-a-bit-lat.patch
      . Fix a crash that happens if the BT headset is the only non-monitor
        source in the system and the last "phone" stream dies.
    - 0700-pulsecore-add-new-card-profile-hook.patch
      . Backport from upstream (commit 7b6260140149) to allow for correct
        profile selection.
    - 0701-bluetooth-bluez5-wait-for-all-profiles-to-connect.patch
      . Backport from upstream waiting for all profiles to connect before
        creating a card.

Before, the P311 headset was connecting, after the update, it's not. Looks like a regression.

When I try to connect the headset (which still seems to pair), I see the little lock next to the bluetooth device for ~0.5 seconds. Then the lock disappears.

Syslog reports:
Jun 30 16:00:40 lat61 bluetoothd[1235]: a2dp-sink profile connect failed for 00:1A:7D:70:08:7E: Protocol not available
Jun 30 16:00:45 lat61 bluetoothd[1235]: a2dp-sink profile connect failed for 00:1A:7D:D0:24:5D: Protocol not available

Enabling the line
AutoEnable=true
in /etc/bluetooth/main.conf
does not fix this issue

[Thomas Mayer (thomas303)]

I worked around it.

I had to remove --purge
bluetooth bluez blueman bluetooth pulseaudio pulseaudio-module-bluetooth

Then I removed all pairing information with devices, both in ~/.config/pulse and /var/lib/bluetooth

Then rebooted

Then paired my A2DP device again, this time with blueman.

Then everything was working.

I think the main problem here is that I once had device discovery disabled in /etc/pulse/default.pa. But that's not a bug in ubuntu.

Issue can be closed.
