I'm running Jessie on Raspberry Pi2. I'm trying to install Pulseaudio 8
from the source, but having problems running it in system mode with Bluez5
with A2DP support.
On startup in system-wide mode, it fails with `"module-bluez5-discover.c:
Failed to load module for device /org/bluez/hci0/dev_AC_CF_85_23_8C_78"`
error when I connect my phone to bluetooth.
If I simply restart pulseaudio under normal user account (pi) using:
pulseaudio -vvvv
and connecting the phone, everything works fine and I can play music via
A2DP from the phone.
Pulseaudio is setup to run as systemd service in
`/etc/systemd/system/pulseaudio.service`:
/usr/local/bin/pulseaudio --system --disallow-exit --disable-shm
--exit-idle-time=-1 --disallow-module-loading
Here is the verbose log output when it fails to load module:

Here is the same section when it manages load the module when I run
pulseaudio under normal user account ("pi").

The only configuration change that I did to Pulseaudio was in `/etc/pulse/
system.pa`, I added this:
### Bluetooth Support
.ifexists module-bluetooth-discover.so
load-module module-bluetooth-discover
.endif
I think I configured permissions correctly too:
`pulse` is added to `audio`
`pulse` is added `lp`
`pi` user is added to `pulse-access`
DBUS permissions are set as follows:
<busconfig>
<policy user="root">
<allow own="org.pulseaudio.Server"/>
<allow send_destination="org.bluez"/>
<allow send_interface="org.bluez.Manager"/>
</policy>
<policy user="pulse">
<allow own="org.pulseaudio.Server"/>
<allow send_destination="org.bluez"/>
<allow send_interface="org.bluez.Manager"/>
</policy>
<policy context="default">
<deny own="org.pulseaudio.Server"/>
<deny send_destination="org.bluez"/>
<deny send_interface="org.bluez.Manager"/>
</policy>
</busconfig>
My phone is paired and connected to bluetooth stack fine.
Can anyone help to understand why Pulseaudio doesn't want to work with
Bluez in system mode ?
