HP G1 800 USDT, 16gb, Haswell Chipset

If anyone has a working EFI for installing Big Sur on an HP G1 800 usdt, would you please share it with me? I have one but have not been able to get the audio working regardless of what I have tried. I think the easiest step for me would be to try someone's working EFI. Thanks! Oh, Catalina worked just fine so it is a bit puzzling.
