STRIX x870e Gaming - Surround Sound Audio Issues - no 5/7.1?

[Yeahdude]

Hooking up my old Panasonic SA-BT200 7.1 receiver and struggling to get surround working. The receiver is tested and working on all channels through HDMI.

I have the Rog Strix x870e-e Gaming Wifi running Windows11

• I would like to use optical audio, which is working, however only 2 channel is supported on this MoBo 

• 'Headphones' jack information is only showing 'L R - Front Panel' as a selection
• 'Speakers' jack information is showing:
  • L R Rear Panel - Selected
  • C Sub Rear Panel 
  • RL RR Front Panel
  • SL SR Front Panel - Selected

*('C Sub & 'RL RR' cannot be selected)

I have reinstalled realtek audio drivers. I have switched Bios setting - Audio IO from  Auto to both 6 channel options.

Questions:

• How can i take advantage of "ROG SupremeFX 7.1 Surround Sound High Definition Audio CODEC ALC4080*". I cannot find this anywhere. I assume its an app, after researching the web, however the only DL i can find is on a random website for Win7 posted over a decade ago. 
• Why is it showing L R & Sub on rear panel and LR RR & SL SR on front panel - *2 different ports
• Could i run 7.1 through HDMI?
• Is this a common issue with this Mobo?
• Should i just give up?

My little project has become something frustrating.

I am in the same situation as you. With optical cable hooked up; I only get 2.1 stereo. I have a Logitech 5.1 sound system.  There is NO mention of the stats for the optical S\PDIF out port. That tells me that it is 2.1 capable only. I think I am going to look into a sound card to fix this.
