Question: I’ve used a Digital Link III DAC (TOS & COAX) for several years and love the sound. Currently, I use a Squeezebox Touch for streaming TIDAL & Pandora with full selection and volume control using iPeng app on my iPhone 6. I wanted to sample listen to TIDAL Master albums using the USB connection port on the DLIII and my MacBook Pro with the TIDAL desktop app. I use Martin Logan powered speakers which have no volume control there. The sound flows through, but it’s loud and I can’t locate how to control the volume from the laptop. Any suggestions/answers from Apple MacBook users or others attempting the same?
Does the USB input not respond like coax and tos? Is the USB circuitry too old for more current laptops?
