Audio Testing

The ASUS ROG Maximus Z690 Extreme Glacial 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 SupremeFX ALC4082 codec, and an ESS 9018Q2C integrated DAC. The ALC40XX Codec is showing up more recently on few AMD X570S and a Intel Z690 chipsets so far. The biggest change from the ALC1200 is that the device is interfaced through USB.

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