Dropouts From Server

Greetings all.  I am having  problems with dropouts during music playback from my server.  I recently lost one of my RAID drives and had to replace the entire NAS server, as well as the dead drive.  I was using a WD MyCloud Ex2 as the server, and for several years had no dropout problems.  I replaced the MyCloud with an updated model MyCloud Ex2 Ultra.  I rebuilt the new drive from the surviving drive, which passed all diagnostic testing  (the rebuild was a twelve hour exercise) and put the new server in line.  Now, often I am experiencing program dropouts.  The PC I am using is an Acer Aspire.  The processor is an Intel Core I7.  I had no real problems before the server failure.  I am controlling everything through Foobar2000.  Any thoughts or suggestions as to the source of the dropouts would be very appreciated.
