Default starting HTPC

Hi, iam currently trying to start a HTPC. At the moment i have a 5.1 surround sound speaker system in my room.

Iam thinking of connecting my PC to LCD TV via VGA (or any other better methods?) so i can play music, view DVDs, downloaded movie clips, etc on the LCD TV instead of my small PC monitor.

Just wondering how would i be able to hook up the surround sound system to my PC, would i need to use a receiver, amp etc, and what type of sound card (atm i have AC99) is needed, would i require HD Audio? I have Mission & Klipsch speakers + Velodyne sub.

yes- unless you have internal or integrated amplifiers in your speakers, you need an amplifier

Yes the PC can act as a receiver, it would be similar to having your PC speakers connected to your computer. However if you already have a home theatre receiver I recommend you use that. Most new receivers have optical in and most newer motherboards that are being used as HTPC have an optical out. If you have an older receiver you could always get a 3.5mm to RCA cable to run from the Line out on the onboard sound to your receiver.

In that case you would need to use a receiver. You can usually find a good deal on ebay or even check out Craig's List in your local area.

The signal coming out of a computer is extremely low amplification and can't drive large speakers.

If it's going to be in a smaller room, you can probably pick up a decent set of powered computer surround speakers to do the trick, but for a larger room you'll want to use a receiver.

So you have this high-end speakers and no receiver? So these speakers are just sitting there collecting dust?

I think you'll want a decent 5.1 or 7.1 receiver to drive those speakers. Maybe something from Harmon Kardon, Denon or Yamaha.

Then assuming your motherboard has SPDIF out, then you get a cable for that to plug into the receiver giving you digital sound.

I had issues using VGA on my Sony LCD TV. It would run 1400x1050 maximum or something, aka a square box. I had to get a DVI-to-HDMI cable so that I could run my HTPC in full 1080p (1920x1080).

Hi, yeah, these speakers are just sitting there now. i haven't not got around to buying a new receiver yet (my last one was bought in the early 90s). I just thought it would be better if i could use the PC as the receiver/amp
