Audio problem after BIOS update

   B450M Pro4 with BIOS version 5.3, Ryzen 7 5700x, Radeon RX 5700xt, 16 GB DDR4 ram
All perfectly functional yesterday with BIOS version 3.6 and Ryzen 5 2600

I updated my BIOS to 5.3 in order to allow an upgrade from Ryzen 5 2600 to Ryzen 7 5700x, but when I did, my audio jacks seem to have lost function on my motherboard. I don't have an audio card and my case audio jacks aren't working either, so the motherboard ones that I used yesterday are really my only option here. When reinstalling the Realtek drivers from the page for my B450M Pro4 motherboard, it doesn't change anything. Device manager doesn't show Realtek drivers, headphones, or microphone.

Please help!

	I flashed BIOS 4.6 instead and when that didn't work I swapped back to the old CPU. Audio is back so I guess it is a fault of the CPU?
