Nice find. I was wondering why sometimes I would not get HDMI audio from some AMD GPUs recently. Looks like it is supposedly fixed in this update.

Good so far, on a PC with a Ryzen R5 3600, B450 chipset, 4x8GB DDR4-3600, and a RX 5700XT (primary) and RX 5700 (secondary), both reference blower models.

Also good on a rig with a 1600 and a RX 480 4GB, which I didn't really test, but was missing the HDMI audio output from the last set of drivers. I guess I should test that out now.
