Well, that’s unpleasant. Let’s try to solve the problem:
Clicks and pops may occur when different sample rates are being used between DPS and your output device. Follow these steps for an easy fix:
1) In your Applications folder, open the Utilities folder.
2) Open Audio MIDI Setup.
3) In the Window menu select Show Audio Window.
4) The left column shows all of your audio devices. Click on each one and set the format to: 44100.0 Hz. Do this for any device that is not already set to 44100.0 Hz.

5) Quit Audio MIDI Setup.
NOTE: Some pro-audio sound devices may not be able to work at 44100.0 Hz. DPS will convert the sample rate to accommodate these devices. If the above steps do not resolve the issue please email me directly at drice@bmtdps.com or create a support ticket.
