So.. I am using the rme converters through an echo layla and I have my echo set to external word clock sync, but with the echo driver you still have to set the sample frequency. Now common sense would tell me that if you are syncing to external sync why would you have any say over the freq? Anyway, do other people have similar setups with other pci cards? Does your card's driver make/allow you set the sample freq. when on external sync?
