AJA Kona LHe on Vegas Audio dropouts

Hi All,
i'm having some puzzling issues with my Kona LHe card and Vegas 10.
I'm trying to dub on a Sony Digibetacam Dvw-A500p a Mxf file.
The playback of the item is perfect on Vegas but after rendering the audio doesn’t come at all through the SDI.
After re-starting the print on tape (using the same rendered file) the audio is back but often has audio dropouts in all four channels of the Digibetacam.
Vegas is running on Windows 7.
The issue appears sometimes not in regular cycles.

Any help is very much appreciated.
Thanks guys!

Hi Fabio,

Sounds like you've gotten the Kona LHe card working with Vegas 10. I just picked up the card and cannot get Vegas 10e to capture with it. I can see the capture with AJA's Machina, but in the Vegas capture (SDI selected and AJA video card) I only get "loading device" and eventually the capture window says "not responding". So it looks like it sees the card but it cannot connect.

Is there special setting that need to be adjusted in the AJA Codex or Machina programs?

Cheers, John
