At my wits end here.
I am using an iMac as a server, connected to a UClock via USB that then connects to a Puccini player/processor for digital to analogue conversion. All was running brilliantly until I upgraded the iMac to High Sierra. Now I get persistent clicks during playback.
I’ve ensured the UClock is recognized by the iMac as a digital source, and selected it at 48,000 hz as a 2 bit 24 integer midi device via the midi interface screen on the iMac. I’ve tried changing the sample rate and still get clicks (more like a signal dropout)
I’ve used the menu on the Player/processor to ensure the UClock is locked to the iMac, and the locked gear sample and UPS shows up in the display window.
I heeded the advice here to make sure the iMac is locked to the UClock master clock, and called Apple for some assistance–their response was to make sure the clock on the iMac is showing the correct time-- not the answer i needed.
I am running DCS Software version 1.21 on the player/processor, and have asked DCS for a cd with the newest software versions for download and eagerly await their response.
I am at the point where i am thinking about bringing the iMac to an Apple specialist and forcing it back to the previous operating system i was using to see if that resolves the problem. The other alternative is to just sell the DCS gear and go a different way and i really don’t want to do that. But, i can’t seem to fix the problem and understandably find it quite annoying…
Any help offered would be greatly appreciated.
