Audio Testing

The ASUS ROG Crosshair VIII Extreme 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 ALC4080 Codec paired with an ESS SABRE9018Q2C DAC to create an exceptional on-board audio solution. The ALC40XX Codec is started to show up on some AMD X570S and a few Intel Z690 chipsets in 2021. The biggest change from the ALC1200 is that the device is interfaced through USB.
