Dropouts with 192/24 from samba share

I have a samba server running on openbsd. I have a Powernode 2I and a Node 2i both connected via wired ethernet to the server (wireless not configured). Playing 192/24 .wav or .flac files gives dropouts in playback where the Node appears to be rebuffering (WAV is worse than FLAC).  96/24 or lower seems to be OK.

On the face of it this would appear to be a server bandwidth or latency problem.  However the server will in general read @ ~60Mbytes/sec (not stunning but plenty for this purpose) and PC hosted players all work fine from the same source. If I host the files on my windows PC (a much chunkier m/c than the file server) then all is OK which would tend to indicate that the Nodes are doing something that is faster on the PC (lots & lots of little reads and/or seeks?).

Is there anything important I should set in smb.conf?  Any other ideas?  (I could convert my files down to 96/24 but that is missing the point)

  Your issue is 24/192 WAV files require 10 mbps throughput from your router to the player just to receive the file in time. You require Excellent wireless signal strength. Increase your network throughput to the player. Please see www.bluesound.com/network101 for more details

  You seem to have missed the bit where I said that the Nodes are connected via wired ethernet - wireless throughput isn't a factor

  It's still your network... check if your router is blocking traffic, check if your PC (which is wired too?) supports full-duplex. Check your router port settings.

  Yes - everything is connected via wires to ubiquiti switches. Full duplex supported everywhere.  I'd believe bad cabling if only one of the Nodes was bad, but they both are.

  As I said everything works if I am getting the files off my PC but fails to the Samba server. (Yes I can get 60Mbytes+ file transfer from the server to my PC so its not the wiring to either of them)

  I've checked on the switch 1G full duplex, no errors on Tx or Rx
