Surround Sound solutions for HTPC

I am almost done with my HTPC, and my future plans included eventually getting a nice Onkyo Surround Sound system that would the HTPC would hook to......however, these surround sound receivers are very expensive and then it dawned on me.....since my motherboard has built in 7.1 surround sound......why couldn't I just buy a set of surround sound speakers for the PC, and use those instead of having to go into a seperate receiver? Would this be a much more cost effective, yet good results way to go?

The speakers that you connect computers to usually have a built in amp. The computer line outs are non amplified, Therefore you need an amplified reciever. Like the Onkyo.

You could go that way. Alot of people used to use the Klipsch Pro Media 5.1 for that back in the day. Now you cant get them because the amp had big problems. You would have to check to see what formats are compatible on some of them. Also the Onkyo will be a much cleaner system. It is basically going from top of the line to mediocre at best. But I do it in my gaming room. With some old Creative Speakers. I say try it out in the store see if it sounds like it will fill the room. Go from there.

$420 for slightly smaller speakers.

Really? What is your budget?

Hmm...I guess everyone's priorities are different. I bought a Dell Studio Hybrid for $300 that does pretty much everything I needed for HTPC.

I don't think $100 surround sound speakers are really any better than TV speakers because the dialogue is so muffled.

I am sure they will put out better sound than just using the tiny speakers that come built into the Samsung TV

For about $125 you can get a Xonar Ds and Logitech x540.
The x540 will give you a decent surround setup (probably the best you can get in your price range) and the Xonar will give you a cleaner output than your onboard audio (less muffled audio, more clear and crisp)

I thought there was a relatively inexpensive receiver out there - $199 (Sony maybe) that has HDMI pass-through - that would work if the card you choose has HDMI, right?

Everyone hears things differently, but a pair of 3" fullrange drivers in dubiously damped enclosures is unlikely to be particular acoustically superior to the typical 2" TV speakers, and both will have a beaming dispersion pattern. On the off-axis, the one with a more tipped up midrange IMO is going to sound clearer. Also, TVs have varying sound quality. As far as setting things up correctly, I'm not perfect, but I strive to use the 0.73 ratio or as close to as I can, toe-in, and use audyssey EQ to make sure the sitting position has a flat response and minimal comb filtering. I only have 3 panels of acoustic foam here set up in the room. I know I could be doing much more, but it's still significantly more than your average joe does.
