Audio Testing

The Gigabyte X570S AERO G separates the audio section with traces to isolate it from electrical noise created by nearby components. This is standard practice for manufacturers who care about quality on-board audio support. Without isolation of the audio components, unintentional electrical noise can be introduced into the audio line, creating unwanted hissing and static sounds.

The board uses a Realtek ALC1220-VB codec, which was top of the line for Realtek before it moved to the ALC4000 series. This is not to say the ALC1220-VB codec is inferior, it just isn't the newest available codec. The biggest change from the ALC1200 is that the ALC4000 series is interfaced through USB instead and should still give a decent onboard audio experience.

The standard 20 kHz test benchmark was performed using RightMark and gives some decent results.
