Distortion - rapid (very loud) clicking with 24-48 files [Resolved]

Mac OS 10.12.5, MacBook Pro, latest Roon version, no DAC, straight out headphone audio.

I’m hearing a loud rapid clicking distortion with any 24-48 bit audio. Other 16-44 files play fine.

The same high res files play without distortion through iTunes, iPhone Music app, iPad.

Any idea what’s going on? Thank you.

You probably need to switch on Exclusive mode.

Could it be you’re currently using system output? If so, activate and select built-in output instead and indeed – as @ruediger suggests – enable exclusive mode.

Thank you both! Switched to Built-in and turned on Exclusive. The distortion is gone. Happy.
