We have the latest 27 inch iMac 5K Retina with 8GB of RAM. Running Sierra 10.12.6. We installed an Intensity Shuttle USB3 to provide output to an Eizo HD monitor and audio out to a small notepad mixer connected to Genelec speakers. When using FCPX 10.4 Video playback via HDMI is fine but the phono audio output from the Shuttle is distorted and crackly with digital artifacts.
When we playback from Media Express the sound and picture are both OK.
We have FCPX settings all correct with the A/V Output set to the Blackmagic device.
Any ideas on what could be causing this? We are using the latest Video Desktop Drivers for Mac 10.9.10
TIA
