We have a GLD-112 connected to Pro Tools 12 through a Dante card in the GLD. I have been able to successfully record 32 tracks from the GLD on to Pro Tools and play back in to the board with no problem for over a year. I took pictures of many of the Mac and Pro Tools settings when in a working condition for documentation. Recently, I have encountered a problem where I can record, but can not play back through the Dante card to the board. We also have a Fast Track Duo output device and I CAN get PT audio out of it.
The only think that I know of that has changed is that we were trying to make some changes for a men’s event and attempted to put a USB to Cat 5 device and a HDMI to SDI adapter. We were not able to make this work and the changes were abandoned. As I write this out, I realize that a USB hub was added and still remains (I will remove this tomorrow).
Any ideas about why I can record, but not play back?
