Best way to get 5.1 surround sound with receiver

[Stevie G]

Hi All

I'm new to the forum and would like your advise on best way to get 5.1 surround sound.

I recently purchased a pioneer vxs323 in the intention to get better sound. I currently have a Logitech z906 speaker system, but not getting the sound i wanted. I have a intel nuc NUC8i5BEH pc, TV a LG 2016 55UH617V and the pioneer receiver. I also have a 4k extractor, but not sure if it will do the job.

My purpose would be to simplify using HDMI/ARC/Optical to use smart tv for Netflix and switch to the NUC to play Kodi/Plex/etc.

I would also like your recommendations for speakers and sub to compliment the entry level amp. Just to hear decent quality that's affordable.

I have got it to play netflix and on the nuc, but sound is stereo and pcm.

I attached some pics for you guys to see
