Just setup the interface and got it to work with my system within a few hours.
ASUS PRIME H570-PLUS BIOS 2001 ME 15.0.21.1549_S. i5-11600K.
Asus ThunderboltEX4 PCIe card connected with PCIe power, USB 2.0 wire, TB header MB wire.
The card came with NVM firmware version 31.0. There’s NVM v36 on Asus page but I’m too scared to apply it. Enabled various TB settings in the BIOS.
StarTech TBT3TBTADAP adapter.
Apple 2m Thunderbolt 2 cable.
Windows 11 Pro, using Asus TB drivers.
Updated the interface firmware to v2 no issues.
Sounds better than my old Presonus Studio Live RML32 AI which still works great.
