Doubt in audio controls of my laptop

[dmanojkmr]

I am using HP dv6 6140 tx
It has 3, 3.5mm jack slot as displayed below.



My doubt is that can we use those 3 jacks to get an input for my 5.1 speakers.
I assume whether this motherboard supports 5.1 audio channel same like other Desktop PC's which doesn't have separate jacks for 5.1 audio instead they use the line in , line out & mic jacks.

^^unless one of these ports is s/pdif you won't get "true 5.1" & only costly ones(like alienware) have this feature.almost all recent laptops support "fake 5.1" though using some driver interface.check your audio driver setting(control panel--HD audio or something like it) & there should be some dolby surround like feature which enables "fake 5.1".
