First of all im new in posting so sorry if i do something wrong.
The last week I bought a Presonus Firepod and dont know how to synchonize it with my computer with word clock through spdif
I also dont know what to buy in order to have spdif imputs and outputs in the computer that admit word clock because I first thought on buying a sound blaster card with spdif but I dont think it could work for synchro.Now I am obligated to spend money
and really dont want to spend too much, I looked for simple spdif in & out PCI cards but didnt find anything, I only found that kind of connections in more expensive and unnecessarily complex cards. 
because i already have mic in and out.Thanks for the time
