HELP! PC to Receiver and TV (sound problem)

[design1314]

Hi guys, please help me find out what is wrong with my surround sound set up for my PC->Receiver. I used to sounds coming from front/center/rear/sub with this set up and not sure what happened and now I would only get sounds coming from front/center/sub, nothing is coming out from the rear speakers anymore. I really think it's because I reinstalled Realtek then the rear speakers stopped working.

I understand this may not be a true 5.1 surround sound but I was happy as it is because I really don't want to use the SPDIF on my PC to receiver due to the PC is about 40 feet away from my receiver.

P.S. Can I use HDMI/HDMI from my PC to Receiver and then HDMI/HDMI from Receiver to TV? But I am already using DVI/HDMI from my PC to TV for video.


Back of my PC (currently using DVI/HDMI to my TV, and using 1 3.5mm stereo/2RCA to my Receiver):

3.5mm stereo/2RCA that I am using:

My PC sounds:

Thank you so much for the help.

You can get optical cable that length
eg http/www.monoprice.com/product?p_id=6735

and the beauty of going the digital route is that there will be no signal loss/interference at all over that distance.
