RME ADI-2 feeding clock info to iMac

[tdbajus]

I'm setting up a little project studio at home, and I have brought my under-utilized RME ADI-2 to be the ins 'n' outs. I have it hooked up through TOSlink, and if I slave the RME to the clock from the computer, everything is hunky-dory. Audio goes in, audio goes out, no obvious clocking errors.

I was thinking I'd be better off if I slaved to the clock in the RME. In AudioMIDI setup, however, the tab for the clock source tab is grayed out, no matter what I do.

Anybody tried this before?

I assume you're coming in through the iMac's 1/8" TOSLINK input?

It won't let you change the clock source because there's no alternate clock input, so the data clock is recovered from the TOSLINK signal. Since the A/D conversion has already been done by the clock in the RME, you don't care about jitter in the transmission to the computer.
