[LAU] Service/user not using PulseAudio

[Iain Mott]

Thanks Chris. I've tried running:

sudo -H -u asterisk bash -c 'unset DISPLAY ; /usr/bin/pulseaudio -vvvvv 
--daemonize=no --start'

and after killing off the pulseaudio process:

sudo -H -u asterisk bash -c 'unset DISPLAY ; /usr/bin/pulseaudio -vvvvv 
--daemonize=yes --start'

But neither get the audio working correctly. The verbose output of the 
instances are as follows:

D: [pulseaudio] conf-parser.c: Parsing configuration file 
'/etc/pulse/client.conf'
D: [pulseaudio] conf-parser.c: /etc/pulse/client.conf.d does not exist, 
ignoring.
I: [pulseaudio] main.c: Daemon startup successful.

If i kill off pulseaudio with 'pulseaudio -k" as user iain and start 
pulsaudio in the same way (rather than having it start automatically 
when using aplay), the output is the same and the audio continues to 
work correctly.

I'm still not sure if /var/lib/asterisk/.config/pulse is being used
