      Thanks for all the input, I have some capacitors already on order and should be with me today. I will get that one replaced and see if there it makes any difference, I will also make up another cable and try another sound card that I have here then I will have a look at doing some surgery on the Si570 to see if it is a solder issue. I will post back when I have been able to do these tasks.

      Many Thanks

      This should be OK.

      This could be a cable problem.

      plus a screenshot of the Test tab in CFGSR.

      All that is needed is said here. "No Si570 connected" Check the soldering of the Si570, particularly pins 7/8. Make sure there is
      not too much solder here, the small contacts each side of centre must not be soldered.
      C34 might be a problem. If the Si570 looks good then replace this first. I'm sure Ebay will produce some. Like

      Or a kit of them, once you get into SMD you'll wonder why you did not before.
