Re: Your system is too SLOW to play this!
It is possible in ubuntu to completely remove pulseaudio and only use alsa. I've got an asus eeepc which I use for skype, removing pulseaudio has made skype useable again. I think you need to enter
sudo apt-get purge pulseaudio
This certainly worked on 9.04 - I haven't upgraded as the 4Gb flash disk is too full to allow it
