Topic: Clocking Issues
I'm running a 2016 trash can Mac Pro, Pro Tools 12.5, an RME Fireface UCX, and an 11 Rack running SPIDF to the Fireface. The Fireface is connected via USB to the Mac Pro. I'm streaming audio off a roughly 10-year-old Lacie hard disk. The Mac Pro is on El Capitan 10.11.6. I'm having issues with popping noises in the audio in my tracks. I believe it is a clocking issue. First off, is there any benefit to using the clock in the UCX as the master instead of using the clock in my computer? My computer says that the clock setting is "default." Does that mean the computer's clock is the master one? If so, what setting should the fireface's clock be set to? Right now it is set to "internal." Also, do the clock settings for The Pro Tools aggregate i/o matter when running the Fireface UCX? Any info would be greatly appreciated. Thanks in advance,
