Cayin iDAC-1 Remote Control

I'm enjoying this little machine but need a remote.  This DAC has two analogue outputs which operate one at a time.  The only way to switch from one to the other is with a remote.  Anyone know how I can get a replacement remote?  Distributors have not been much help so far.  Also considering purchase of a universal and programing it, but seems overkill for one feature.  Many thanks in advance.
