What I do is take the word clock from the S/PDIF receiver and use it to start a counter which is getting clocked from one of the fixed clocks. At the end of the word clock I then compare the number comming out of the counter, I check ranges, if its greater then this number and less than that number the sample rate 44.1, if its between a differfent set of numbers its 48 etc. I implement this in an FPGA because I'm doing practically everything in one so its already there. If you don't have an FPGA you could implement it in a CPLD or a small processor like a PIC.
