Windows XP No Sound

Have used Audacity on my desktop but now have it on laptop and I get no recording.
As soon as I bring up Audacity my laptop speakers sounds like it goes mono and it also wont record any sound on Audacity. It shows no action in the recording feed so its not on playback its on record.
Im thinking it is a setup issue. I use this on a desktop that works perfect but my laptop isnt working. I have Windows XP. Are there basic settings I need to check to get it to record?

Please try reading carefully through this .

If you need help after that please tell us exactly what you are trying to record and how you are trying to do that.
