Can't hear anything

So, all of a sudden I couldn't play music using Rhythmbox. It would open, I would click on a song and it would say it was playing, but nothing happened. The track clock stayed at zero.

Thanks to this link on the ubuntu forums, I think I have it sorted.

System->Preferences->Sound and changed all the options to ALSA. This has resulted in being able to hear music at the same time as being on the internet etc. Tracks take a couple of seconds longer to start than I am used to, but I'll monitor it for a bit and maybe look at a couple of other steps when I am not busy.

Fonts
