Ubuntu netbook problems playing AAC encoded audio.

Had to repair a netbook for on of my friends kids, their windows xp key was unreadable so thought I would install Ubuntu Netbook edition instead.

Only problem was that when playing back any AAC / MP4 encoded audio 'totem' would crash with following errors

pa_stream_cork() failed

pa_stream_writable_size() connection failed

Quick search lead me to these sites:

https://bugs.launchpad.net/ubuntu/+source/gstreamer0.10/+bug/659551
https://launchpad.net/~diwic/+archive/fighting-rewinds

Temp fix suggested there 

sudo apt-add-repository ppa:diwic/fighting-rewinds
sudo apt-get update
sudo apt-get upgrade

This fixed the problem.
