RPI4 + hifiberry Digi2 Pro

I had a working system with hifiberry digi2 pro, optical out going to my dac. After a few hours of playback, it stopped outputting sound. Now, there is silence. My Ropiee setup has a touchscreen,RPI4 and the Hifiberry HAT. Even the coax output is silent.

How can i troubleshoot if the HAT is dead? I can get sound out of the RPI USB interface, but I don’t know what to do with the HAT.

Have tried many reboots, configures and also tried to set the HAT to none and then back to the HifiBerry board. Almost ready to get the allo digial board…
