Sync source set to SPDIF.
Using a focusrite saffire pro 24 dsp with logic and mix control software.
Can't hear the crackle when playing through my cab. Crackle appears on recorded audio as well as when monitoring. tried DAW monitoring and Direct Monitoring and still getting a slight crackle.
Gave the SPDIF cables a push to make sure they were connected properly, Seems like they are.
Any other suggestions? Thanks for taking the time to read.
