No HDMI sound with new bios

   Actually my kid has the same issue, but mobo is different - AB350M Pro4, one day after BIOS flash sound disappeared from discrete Sapphire Pulse RX570 card.
Hopefully new BIOS, which fixes the issue, will be released for that mobo as well. Fingers crossed.

	Try drivers.softpedia.com and search for previous bios for your mobo.

	I maybe wrong, but it Looks like Asrock have removed all windows bios updates from download page only leaving instant flash.

	I had same problem with Bios 3.1 and 3.2 for the Fatal1ty B450 itx and saphire pulse card with 2400g cpu. I managed to downgrade using the windows version. HDMI sound came back again with version 1.7 bios.

	Hello I flashed to bios 5.60 on my Asrock AB350 gaming ITX motherboard and now HDMI sound doesn't work. It won't let me flash to bios 5.30, it says invalid file. How do I downgrade to bios 5.30? Is there a beta bios I can download? Thank you :)
