Which clock is running my system?

Hello,
I have an M2tech Evo usb to spdif converter. The Evo has two clocks inside the unit. If I have the digital signal running through the Evo and into my dec, which also has clocks inside, which clock is controlling the D/A conversion? Is the dac slaved to the clock from the Evo, or is the Evo simply passing the clock information onto the dac clock, which is acting as the master clock for the digital front end. This is very confusing. Thanks in advance for your help.

The Clock in your EVO is the Master Clock. However, there may be ASRC or asynchronous upsampling hardware inside your DAC that re-clocks the data. In that case, both EVO and DAC ASRC clocks are important. You didn't give any details about your DAC, so we can only guess.
