Audio Testing

The ASRock B550 PG Riptide 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 ALC897 Codec, which is close to the bare minimum for the on-board audio of a modern computer, not just OS clicks and beeps. The RightMark test results are surprisingly good. Now, the sweep test is only 20 Hz to 20 kHz, which means most things get a pass, and that is also about all a human can hear. ASRock gets a pass because even though the ALC897 is near the bottom of audio fidelity listings, it clears the 20 kHz sweep with acceptable noise levels.
