Quick question what does U500 do on the main PCB?

When I ran a couple of additional tests using the routing utility software I discovered that also the 4 AES/EBU channels encounter the same problem.

When using an audio generator patch I could hear it in the background through all the noise on the outputs.

it sounded similar if you use a digital protocol without proper Sync (even in this case we used analog outs with stable/locked in wordclock).

I took another look at the main board since „both“ analog/digital boards in this area are failing it had to be something they share.

The only single socketed IC in this area of the board was U500 so I took it out and re-seated it and guess what – All is well again no issues with the 4 ins/outs analog/digital no nasty noise just pure enjoyment:)

As the distorted signal reminded me of sync issues I wonder if U500 is (partly) responsible to generate the Clock/Sync for this part of the H8000FW?
