MSI has released another BIOS for the X570-A PRO. Evidently more bug fixes are being presented.
- Fixed HDMI audio lost issue when use AMD RX 570
- Improved USB sound card compatibility
There are no release notes as usual. The experience of using the motherboard make it clear there are issues.
TESTING VIDEO CARDS
No luck with the GTX 690 or the R9 Fury. These cards cost a lot of money and any reasonable person would expect them to work. So MSI and AMD are liable for inoperable hardware.
