Hi
Don't worry about that, your problem is of a missing Sound Driver.
You can select your Presario 700 version from this list here:

Then go for sound driver, and download the sound drivers presented, try one after another untill you get you Sound working fine.

SOURCE: no internal sound but it working in headphone

you need to reinstall the audio driver ,some time it happens the audio comes from headphone and internal speakers stops working.
if you are using win xp, you need to uninsall the audio driver from device manager and then you need to install uaa driver and then conexant high defination audio driver. i m very much sure it will resolve you issue. in win xp , the audio driver has to be installed manually from device manager..here are the links for audio
