Shell scripting DBus error

[subluminal]

I'm trying to control Banshee, my audio player of choice, over a web interface. 'banshee --play' works just dandy from a shell. My PHP looks like this:

 

<?php

$output = shell_exec("banshee --play");

echo $output;

?>

 

Output looks like this:

 

[Warn 23:11:45.015] DBus support could not be started. Disabling for this session. [info 23:11:45.033] Running Banshee 1.2.1

 

I tried wrapping the same thing in a shell script, which works from the command line. I get an identical error when trying to execute from PHP.

Likely to do with the fact that the apache user does not have sufficient permissions to access your audio devices. You'll need to add this user to the relevent groups.

Thanks. Tried adding to audio-- same error. Anything else?
