Optical S/PDIF to 5.1 HDMI adapter?

[Silent Night]

TV: 2011 Samsung PN64D7000 Smart TV
Sound System: iCinema i-HD5 (I got it for free 3 years ago and it has been sitting in the garage for 2 years, I did a Google search on this company and it turned up nothing tangible. Pretty shady stuff if you ask me, not what this post is about though.)

Hi, guys I'm new to Tom's Hardware. I am a pretty techy guy and I have no idea why I haven't joined this site in the years I've known about it. Today I thought "Why not?". For questions I had been using Yahoo answers and I think the people on this site will be better with this kind of stuff.

Recently I've been taking courses to become a music producer, and since I've been taking these courses I have been much more picky when it comes to audio. I have been listening to audio out of the built in speakers in this TV for the longest time without it bothering me, and now it does. I decided to hook up this sound system I got awhile ago.

The question:
My TV only has an audio out in the form of an Optical S/PDIF output. The input to get the 5.1 audio on the sound system is HDMI. What adapter should I get to convert the S/PDIF to HDMI while maintaining all 5 channels and not just get 5 speakers playing the L/R channels?

I found these online:
Belfan adapter
Monoprice adapter
Ultra adapter

I want to know if any of those will maintain all 5 channels or if not get a recommendation of one that will. If maintaining all 5 channels isn't possible then I will accept defeat and just buy one of these so I need to know which is best anyway. Thanks!

The Ultra adapter doesn't specifically say if it will do 5.1 but it almost surely will. The Belfan says it does so it would be safer to use it. Monoprice link did not load, There is a potential problem with all of these in that they may also require a video input to work though.
If you have external sources (set top box, BD or DVD) then connect those to the 5.1 with hdmi and connect the HDMI out to the TV. You only need the adapter for internal TV sources such as over the air tuner or smart functions.
I wouldn't expect anything great from this system but since you have it you might as well give it a try.

I didn't see where it said that the Belfan one supports 5.1. I looked again still can't find where it says that. If you say it does I'll take your advice and go for it. Thanks!
