I am trying to connect a QU 24 to a QU 5, and have followed all of the steps I believe are required to do so: I have plugged a shielded Ethernet cable into the sLink and dSnake ports, and have changed the clock source from internal to sLink on the QU 5, however I am getting an “Audio not synchronised” error, and I’m not sure how to fix this.
Is anyone able to help me out?

I have previously had this working, and have tried many different cat6 cables, and different software versions on both consoles (both up to date, and on older versions)
I also factory reset both consoles before trying anything so no old configurations should affect this
