Please help me with home theatre / LCD / Computer setup driving me mad

Hope somebody knows the answer/s. Ok here is the setup i'll lay it out for you:

Computer mobo GA-MA790FXT-UD5P , audio specs:

1. Realtek ALC889A codec
2. High Definition Audio
3. 2/4/5.1/7.1-channel
4. Support for S/PDIF In/Out
5. Support for CD In
# Blu-ray playback supported by high quality 106dB SNR ALC889A HD audio
# Supports Dolby Home Theater audio to enjoy a rich surround sound experience

Home theatre system (cheap one but i do like the sound when it works):

Panasonic SC-PT70 5.1 surround sound dolby digital supported

Input/ Output
HDMI Out 1
Audio Input. 1 (AUX/TV)

LG M237WD 23" Widescreen LCD TV/Monitor Full HD

Expansion / Connectivity
* Interfaces: 1 x VGA - 15 pin HD D-Sub (HD-15) ¦ 1 x HDMI - 19 pin HDMI Type A ¦ 1 x component video input ¦ 2 x SCART - 21 pin SCART ¦ 1 x DVI-D - 24 pin digital DVI

How i'm currently setup is i've got hdmi luckily on my radeon 4850 cards and one of them is connected to the LCD (it only has one input on the tele) I want to connect the 5.1 speaker system through to these but i cant work out how it's only got one HDMI out port and that can't go in the tele as theres already one in it and it won't go in the computer will it? The only other connections on the theatre system are RCA but i heard this is only 2 channel and i dont want that and SCART but wtf kind of sound will i get out of that if any? The only other connection is a 3.5mm jack at the front that ive managed to link to the computer front headphone jack to get some kind of stereo emulation sound coming out but i'm sure its not the real deal. Please help i want a high quality audio solution to this puzzle. I bought HDMI cables extra and a 3-1 HDMI switcher too but couldnt get that to work with all this.

Forgot to add I got this also:
Neet® - 3 Port HDMI AUTO SWITCH BOX with REMOTE - 3x1 HUB (3 way input 1 output) - 1080p Full HD - v1.3b HDMI Switcher

Kind regards

  1. Your receiver only has HDMI out, so there is no way to get audio through your speakers using that. Your receiver isn't a true 5.1 system anyway (it's virtual according to the specs sheet you linked). Probably your best bet would be to connect that 3.5mm jack from the PC sound card (integrated or discrete) to the to A/V ports in back of the receiver.
