The issue you're experiencing could be due to the 3.5mm line-out connector not fitting properly in your Gigabyte X570 UD. Adjusting the position of the headphone jack might help, but if the problem persists, it may indicate a manufacturing defect or compatibility issue with this specific model. Since this is your first build, it's possible the connector design or placement isn't ideal for your setup.
