Just a few thoughts.
Have you tried another optical cable to make sure the one your using isn’t bad?
Do you have the latest drivers for your motherboard?
If your motherboard has HDMI audio make sure it’s sending the digital audio to the SPDIF output and not HDMI, it may not support both at the same time.
If your receiver has HDMI why are you messing with optical audio?
If you haven’t, try sending something other than PCM over the optical to see if the receiver sees that.
If you have access to another device that has optical output see if the receiver recognizes that. Also try another receiver if you can access one.
I think your motherboard supports an add-on SPDIF dongle that has both optical and coax outputs you might try ordering one to see if that works.
Lastly you might try a dedicated sound card. Many people don’t ever get there onboard audio to work properly.
I’ve been through HTPC audio hell so I feel your pain.
Good luck,
Dean
