Audio Testing
The ASRock Z390 Phantom Gaming X lives up to the standards I expect from modern motherboards and has the extras I like to see—namely, the S/PDIF Out port. Unfortunately, I could not remove the cover from the audio cluster without significant risk to the board.
Audio for this board is provided by a Realtek ALC1220 audio codec.
