How to Setup a Laptop to Projector and Home Theater?

[BlazeHN]

Hello friends.

I have a Laptop and a 5.1 Home Theater wich only have Optical Input (no HDMI input) and I plan to buy either Optoma, BenQ or Acer Projector. But I'm intrigued on how will I connect all this to get 5.1 sound from the content I send from my laptop (movies and games) and 1080p video on the projector. Wich kind of conection, cables, etc. I have to use? Do I need to buy an aditional receiver to solve my Home Theater optical input only problem? This are my items:

- Laptop: Lenovo Ideapad Y510p
- Home Theater: Samsung HT-E550 Optical Input only (no HDMI Input)

3 Posible Projectors (not sure wich one yet, suggestions?)

- Optoma HD131Xe - $747
- BenQ W1070 - $897
- Acer H6510BD - $750

I dont know if I need some kind or receiver (to send audio from Laptop to Home Theater), something like this maybe?

Something like this might give you what you're looking for. Audio out from your laptop via USB to the external sound card. From the sound card, optical output to your current Home Theater set up.

Thanks Wolf, but one question, dont you think "this item" could solve the problem too? It haves a HDMI input and a HDMI output and Optical (SPDIF) output (and its cheaper). Description of the item says: HDMI Supports Full HD 1080P + 3D and SPDIF supports Upto 5.1CH Dolby Digital 5.1CH, DTS 5.1CH & Dolby Digital Plus Audio

Also I just realized I wont have a way to watch my normal Cable TV :S where do you plug the coaxial end of traditional cable TV to watch on a projector? (sorry I'am new on this)

The HDMI audio extractor will work fine but if you want to use cable TV then you will need a HD cable box with HDMI output. You can get an HDMI switch with the same audio extraction as the adapter. Simpler in one box like this

Whoa! I think that is EXACTLY what I was looking for, but one question, I plug my RF Cable TV part to that yellow Coaxial slot? (its an input slot?) because it looks kinda different (the slot and the RF part).

Additionally how will I select TV? I mean the remote only gives the 4 HDMI input options, where is the TV (Coaxial) one?

Sorry if my questions are noob ones =/

Ok I think I'm almost there, look at my next diagram:

Looks like the only thing I need now its a way to plug in my coaxial TV cable to a receiver or a way to convert that coaxial cable to HDMI.

Wonder if "this item" could do the trick? Since it have a Coaxial Input and a HDMI output. (sadly its a big thing with many slots I would not need, wish I could find a "all in one" solution).
