I have installed the new Radeon Software Crimson ReLive Edition Beta for Blockchain Compute Driver for Windows® 10 64-bit.
I'm currently using two RX Vega 64 on my motherboard using PCIe x16 and PCIe x1, after installing the new driver I am having issue with High Definition Audio Bus not loading correctly with the card on PCIe x16.
Screenshots from Device Manager on Windows 10 Pro:
Please note that if I install the current driver (latest stable release) there is no problem with High Definition Audio Bus.
Also I have tested, if I put both cards on PCIe x1, they will work fine and there is no problem using the new Beta driver.
Any idea on how to get the card working on PCIe x16 with the new Beta driver?
As the release notes say,
"This driver is provided as a beta level support driver which should be considered "as is" and will not be supported with further updates, upgrades or bug fixes".
