Squeak is treated: * USB insulator, by the way, which was not included in the price; * A motherboard that has a dedicated socket for DACs. (For example, Gigabyte calls it DAC-UP or DAC-USB). * USB hub, with additional power supply; * "Crutch": add a 320 ohm resistor to the ground of the USB plug, connect 5V to ground with a 50V 10uF capacitor.
