Comment 10 for bug 1325282

It seems that on Kubuntu Trusty, by default two pulseaudios are running:
$ ps aux|grep pulse
julius 3414 1.1 0.1 588164 7056 ? S<l 19:38 0:56 /usr/bin/pulseaudio --start --log-target=syslog
julius 3969 0.0 0.1 502228 5520 ? S<l 19:41 0:00 /usr/bin/pulseaudio --start --log-target=syslog

The log-in process start pulseaudio 2 times and the presence detection appears to be broken.
