Terrible problem with digital clicks - could you advice ?

[Notefarm]

I am not sure if this is the right answer but I know that if I don't set my sample rate to the correct setting when using my ADAT light pipe in for an extra 8 ins, I get cliclk and pops.
May be that might help.
Just a guess.

What do you exactly mean ? I have sample rate set to 44,1 permantly and have not ever changed it ...

What happens if you go from the Rosetta straight to the Mini DAC (taking PT out of the equation).. any pops and clicks?

I tried it in another way now. When I listen to something via mini DAC, occassional clicks happen. I switched back to 001 outputs (quite a big sound "downgrade" [img]images/icons/shocked.gif[/img] ), no clicks ...
Have not tried with recording yet, but I am almost sure that without mini DAC connected the clicks will not be happening. What could it mean ?
What do you mean by connected Rosetta and mini DAC directly ? What would I hear then when PT is bypassed ?

Rosetta A to D SPDIF or Toslink to Mini DAC -- With the Rosetta as the front end - it's the clock source for all devices after it in the chain. If you just monitor straight from into the Rosetta D to A to the Mini DAC without anything in between.. does it still have a clocking issue -- this removes Pro Tools as an issue, or identifies it as somehow not feeding the Mini DAC with a good clock source. I'm taking it that you've set the Mini DAC's clock source setting correctly.

I did as you suggested - connected Rosetta and mini DAC via SPDIF cable and fed Rosetta with a sound - no clicks.
Then I again connected Apogees with PT and changed the new luxurious Sony optical cable connecting 001 and mini DAC for an old thin simple one, listened for almost ten minutes - so far no click. Could this be an issue ?

Cables (actually usually the connectors) could definately be a problem. See if it's better with the different cable for a few days.

I have Apogee Rosetta and Apogee mini DAC connected via lightpipes to 001. Hardware settings: optical format ADAT, sync mode Optical. In PT: input Optical 1-2, output Optical 1-2. Although mini DAC sounds awesome, since adding it to my chain, I experience digital clicks sometimes less, sometimes more often, sometimes they stop for some time, sometimes it is unbearable. During recording (they are recorded), and also during listening. I changed a cable, still going on. What can be the problem ??
