32kHz sample rate
Using MDFourier 1.08 with this reference file.
The 32kHz sample rate is most commonly used by licensed software. It is upsampled to 48kHz in hardware prior to final output.
The nominal sample rate is 54MHz÷1124, rather than 54MHz÷1125. This is reflected in the frame duration of the standard equipment test.
A 15kHz white screen was displayed to induce audible noise.
ASUS PRIME X570-PRO & ProArt X570-CREATOR WIFI
Using ALC1220 (S1220A).
This sound card serve as our analog reference.

48kHz sample rate
Using MDFourier 1.08 with this reference file.
The 48kHz sample rate is most commonly used by homebrew software and streaming audio in licensed software.
The nominal sample rate is 54MHz÷1124, rather than 54MHz÷1125. This is reflected in the frame duration of the standard equipment test.
A 15kHz white screen was displayed to induce audible noise.
