Comment 47 for bug 190754

Following from Helge's comment I did :

sudo apt-get purge pulseaudio && sudo apt-get install pulseaudio ubuntu-desktop

(ubuntu-desktop meta package depends on pulse audio so needs to be reinstalled after purging pulse audio) doing this completely removes pulse audio and its configuration files and then installs it again. This appears to fix the problem with stuttering audio. Unfortunately I forgot to test after the first reboot after doing this and so it could have been one of the updates we have had since. Could someone else who is having this problem please try and see if this really is a solution?
