Audio Testing

The MSI MPG Z690 Carbon WiFi 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. The ALC40XX Codec is starting to show up on some AMD X570S and a few Intel Z690 chipsets I have seen so far. The biggest change from the ALC1200 is that the device is interfaced through USB.

The standard 20 kHz sweep was used as RightMark yielded strange results on multiple motherboards above this. While I would have liked to provide a wider range to show off what this audio codec and DAC combination is capable of, I didn't because I couldn't trust the results to be accurate.

RMAA results are below:
