error during AAF

Hey everyone,

ive been trying to export an embbeded AAF file to my sound designer, however whenever i run the export process i keep getting this error message:
"Cannot embed audio source "File path" because an error occurred when writing essence data. Premiere ASL error number: -2147286767."

so far ive tried:
1) Render and Replace all the audio on the timeline

2) transcode each channel seperately into WAV

3) remove transitions and effects or render with audio clip effects

4) exporting with complete files

5) change the bit and sample to 16\24 and 48\96KHz

6) checking the tape names box

7) copying the info to a new timeline

😎 compying the info into a completely new Premiere project

but nothing seems to be working.

the only thing the works is when i export the AAF with Seperated files instead of Embedded.

the sound designer really preferes to work on an embedded file, and i see no reason for it not to work, but so far cant fix it.

can anyone please help?

thanks in advance!
