I think we are describing synching on digital input stream, not technically wordclock. The Apogee has wordclock connectors; you are likely not using them.
I use a Lavry Blue instead of a Rosetta 200 on my 2011 MacPro 10.6.8, although I have some experience with the 200. I have generally been successful setting to digital input within each audio editing application I use (Sound Studio, Reaper, Adobe Audition, etc), then checking the AMS settings. However, when upgrading to Sound Studio 4.5 recently, it gave a tick sound every 30 seconds, which was only on the sound monitoring during recording, not actually on the written file. Sound Studio had no answer, but recommended moving to OS10.7x. I have downgraded back to SS4.2.
So, what exactly are your synch settings in your applications, and then what does AMS show? Is the sound constantly fuzzy and distorted, or do you hear clean sound with random clicks? Or something else? You have tried various applications? What exact model MacPro do you have (System Profiler, i.e. MacPro1,1)? You are not using the Apogee firewire interface, are you?
thank you so very much for caring!! I´ll try to provide as much information as possible:::
sorted it into ABCD
A: THE MAC
Machine is a MAC PRO5,1 built mid 2010, Quad Core Intel Xeon 2,4 Ghz
System is 10.6.8 (had the same issues under 10.7.x, too)
i get those clicks every 10 - 15 Seconds, some left, some right,
i get them in every audio, e.g. quicktime movies., itunes songs ... no so frequently, but they are there ..
Sound is otherwise ok, no fuzz or other artefacts than the clicksies ...
borrowed a Fireface UC just to be sure ... no clickies at all.
in AMS i created a "Hauptgerät" (Main Device or whatever its called in the US System)
DIGITAL INPUT (with a Clock-Icon)
DIGTAL OUTPUT (With a wave icon)
With MAIN DEVICE highlightes, the puldown menu on the right says: "Source for clock : Digital Inpit (inegrated)"
In the list of audio-devices below Digi-Out and In boxes are checked, AMS puts a checksign into the "resample" of Digital Output ... don´t know why ...
If beneath MAIN DEVICE i highlight the "digital input" it shows on the right:::
source: Internal Clock
Format: 44100,0 kkz 10 Channel, 24 Bit
But AMS crashes everytime i highlight "digital input" (thats a new "feature"!)
C: ROSETTA 200
says Wide/Narrow , meaning "clock locked"
Sample Rate 44,1
SRC is not on, neither on DIGI nor ANALOG outputs
WC/IO ist not set to external
(i don´t know the rosetta so well, it just always worked, so i never had to dig deeper)
as far as i know and reseached there is no place in Logic where you would talk care of
clocking (apart from MTC)
I/O Buffer is 256 Samples, but anyway, i have the clicks on every audio from every application
so, thats all i can offer you ... can you think of whats going wrong here?!?!? i do hope so ...
thanks for offering your help ,,, much appreciated!!!
