Got some trouble with clock "mismatch of sync source"

[soundonthemoon]

Hi there,

I got some troubles with my pt HD,
just bought a new ad 16 x and now i got this message "Too many slots on the TDM2 bus - could indicate an unplugged audio interface or a mismatch of sync source and session sample rate. (-6075)"

So there is my setup:

I got a PT HD 3 with 3 da16x (each one are connected to a pci card) my ad16x is connected to the 2nd DA16X.
I also got a big ben who send clock to all my converters. But the big ben is synced from another device (the weiss afi1).
Off course all the apogees are set on external wordclock even the big ben and the sync i/o too.

In my session setup window the wordclock source is set to wordclock...

I really don't know what to do cause when the error window appears i just click on ok and i can going back to my work without troubles...

Thank you..

Quentin
