I suppose a likely cause for the problem is that the asterisk user has
no ~.config/pulse directory. How can I get around that?

Hi,
Another Asterisk PBX related question. I have the Asterisk service
periodically sending System commands on the host machine when
particular phone extensions are called. The Asterisk service is run by
the user asterisk. I made asterisk a member of the 'audio' group so
that it can use 'aplay' with the System command. eg.
System(aplay -c 1 -D pulse /home/iain/sounds/line1.wav)
This plays OK but plays on the laptop's internal hardware rather via
PulseAudio. Jack is running and is configured to use an external USB
sound card and the PulseAudio Jack Sink.
If I run the following as user iain, it plays correctly through the USB:
aplay -c 1 -D pulse /home/iain/sounds/line1.wav
However via the Aterisk service, or by running the command in a
console as asterisk, it plays through the internal speakers. eg.
sudo -H -u asterisk bash -c 'aplay -c 1 -D pulse
/home/iain/sounds/line1.wav'
I don't know if the "-D pulse" option is necessary, I'm trying lots of
things...
As well as the audio group, I've tried adding asterisk to the pulse
and pulse-access groups, but it doesn't help (and yes, I logged out
and in again).
If i run the last code given above with aplay in verbose mode (-vvv),
it throws the error:
xcb_connection_has_error() returned true
But this Is not error because adding "unset DISPLAY ; " to the start
of the command removes the error but it continues to play through the
external speakers. Here is the print for the command:
iain@samsung:~$ sudo -H -u asterisk bash -c 'unset DISPLAY ; aplay
-vvvv -c 1 -D pulse /home/iain/sounds/line1.wav'

Any suggestions please?
