[PROBLEM] Samba setup.....Idiot guide required??

[Nutul]

No. as user/password as the credentials required when you connect to the share from your windows PC.

.....used same....pi and moodeaudio
They seemed to be the obvious choice of 'credentials'........??

Hmm,

I kindly ask you IF YOU CAN TRY to use root / moodeaudio. Not what you have done, or think it is obvious.
