Sync I/O messing with 192's dig output w/workspace

[Gio Mix]

Hi Gang,
Since installing PT 7.2.1 on an intel 2x3Ghz (4GB RAM, OS 10.4.8)
When I try to audition files in workspace (say a set of FX or some Music Libraries)
the 192 stops outputting sound and digital reference out the Dig cards. I clock my console (Yamaha DM2000) off of the 192's AES output 1-2
every time I click on the play icon the console freaks out, my Digital clock monitor freaks out, and I cant hear a thing.....
This is when my session is set to SYNC I/O, Video Ref (I send black burst to the whole facility) and everything is locked correctly.
Now,
If I set my session to 192 INTERNAL, no problem what so ever, none.
Has anyone had this problem?
is there a firmware to setup for the Sync I/O
Thank You

Why not use the word clock output of the SYNC I/O to clock the DM2000? It may resolve your problem, and word clock is more stable than an embedded AES clock as well.

will try it and see if it works for all sampling rates
Thanks

this is exactly how we do it w/ our DM1000. it works up to 96K so far...haven't tested
it beyond that.

every once in a while, the console forgets what it's doing and i have to go into my
PT session and "jog" my clock source setting. we typically use "internal" as our
clock...so i'll flip it to "sync i/o" and back to "internal" and it seems to send
the correct message to the DM1000 (the DM1000 was muting the audio when
it was glitching...but the clock-toggle clears it right up)

hope this helps,
marty.
