[Bug 1438510] Re: [REGRESSION] bluetooth headset no longer supports a2dp in 16.04 xenial and 16.10 yakkety

[pasimako]

I've been using the script from #57 in 16.04 & 16.10, but in 17.04 I
switched to GNOME and now the script fails since it cannot find an a2dp
sink. After some research, it seems that the problem is with GDM
starting its own pulseaudio process
(https://bbs.archlinux.org/viewtopic.php?pid=1526658#p1526658). If you
think you might have the same issue, first check your pulseaudio
instances:

$ ps aux | grep pulseaudio
gdm     2578  4.3  0.1 2350536 12896 ?       S<l  15:40   2:10 /usr/bin/pulseaudio --start --log-target=syslog
user     1533  4.3  0.1 2350536 12896 ?       S<l  15:48   2:18 /usr/bin/pulseaudio --start --log-target=syslog

If you see a process owned by gdm, you can try to disable pulseaudio
spawning by gdm during startup:

$ sudo nano /var/lib/gdm3/.config/pulse/client.conf
autospawn = no
daemon-binary = /bin/true

$ sudo chown gdm:gdm /var/lib/gdm3/.config/pulse/client.conf

Restart and #57 should now work.
