[AppleALC] Internal speakers not working on Optiplex 3010 MT

[sincerehumanbeing]

Hello, I installed the latest Big Sur on an Optiplex 3010 and everything except sound seems to be working after following dortania's guide. Here are my specs:

• Motherboard: Dell OEM, H61 Chipset
• CPU: Intel Core i3-3220 3.30 GHz
• iGPU: Intel HD Graphics 2500
• dGPU: AMD Radeon HD 7870
• Ram: 8GB DDR3, 1333 MHz (2 DIMM)
• Storage: PNY 120gb SSD
• Network: Realtek RTL8111E-VL
• Sound: Conexant CX20641

And here are some things I've tried:

• I found my codec listed in acidanthera/AppleALC and I tried both layout-id’s (under DeviceProperties > PciRoot).
• SSDTTime to fix IRQ conflicts. I added oc_patches.plist to my config.plist

With layout-id: 13, the “internal speakers” sound output shows up and headphone jack is working, but no sound is coming from the internal speakers.. Any help would be greatly appreciated

I've attached my EFI below.
