Motherboard question

Hello


I have this motherboard and I was wondering if the audio card is part of the motherboard or something "alone?" The port is broken and I can't connect my external speakers to it anymore. I did use duck tape to hold it before, but now I can't have stereo sound if I do


So I'm not sure if the audio card is part of the motherboard, if yes I would have to find another MB to replace just the audio port? (the plastic ring outside is broken, that's why)


its the Sony laptop that got that small problem. The Compaq is inside that seem defective.


Also I notice that the Compaq is slower to respond to command. I mean like I click on a link and its slower to respond compare to the Sony.



It seem for what I read on the two specs that the Compaq is like 1000 Mhz slower that the Sony?


Can I upgrade the CPU for a more powerful?



I think both have 6 gig of ram, the max for bot is 8 Gig.



Thanks
