not much luck so far; I keep getting audiooss : buffer underrun.  
I am running on a gigabyte bard  VIA chipset/celeron CPU  which  can be a bit 
temperamental.  I shall try the  card and the nas server  in another board 
and  see if I get lucky.  In the meantime  any other suggestions you might 
have I will be happy to give a whirl.

regards
