Public bug reported:

$ system-image-cli -i
current build number: 253
device name: mako
channel: ubuntu-touch/devel-proposed
alias: ubuntu-touch/utopic-proposed
last update: 2014-09-24 00:51:54
version version: 253
version ubuntu: 20140923.1
version device: 20140923.1
version custom: mako-0.6

I noticed that when playing audio via the speaker/headphones the CPU
usage is higher than when playing via a paired bluetooth speaker.

Speaker CPU usage:
Format pulse media-hub
m4a 30  20
flac 30  15
mp3 25  20

Bluetooth Speaker CPU usage:
Format pulse media-hub
m4a 10  15
flac 10  10     
mp3 15  10

It has been suggested that changing the buffer size may resolve this
issue.
