"unable to detect clock source" interrupts recording when using external sync

[Tobias Eichelberg]

First of all: kudos to AVID for updating the Eleven Rack driver!

However, I have found a bug in the driver - I use the S/P-dif inputs/output for Eleven Rack and since it does not have a dedicated wordclock input, I'm using the S/PDIF input as clock source as well of course.

Now every 160 seconds or so the hardware will loose sync and the driver reports "unable to detect clock source". Just for less than a second. That's enough however to stop any recording done through Eleven Rack. The same thing happens when I clock to the AES input instead.

Anyone else discovered this bug?

I'm running OS 10.15.7 on a late 2019 MacPro, the device is connected directly to a USB output on my Mac, not through a hub.
