Public bug reported:

phablet@ubuntu-phablet:~$ system-image-cli -i
current build number: 166
device name: mako
channel: ubuntu-touch/devel-proposed
alias: ubuntu-touch/vivid-proposed
last update: 2015-04-09 16:57:42
version version: 166
version ubuntu: 20150409
version device: 20150210
version custom: 20150409

This is specially annoying as it happens every time you change the
volume without an active notification. Side effect is that it fires up
media-hub, that initializes gstreamer for not really playing anything.

Just press volume up/down and check the unity8/media-hub logs:
