XPS 400 Soundcard

Hey,

 

I was wondering what type of sound card I had in my XPS 400. I did not upgrade at purchase, so its the defualt I guess.

 

Also, I am using this PC as a HTPC so what is my best option for audio cables that will connect to my TV/Reciever?   

 

Can I use Digital Coaxial Cables?

 

 

Thanx
