Random distortion (not another blackburst issue)
Hey guys,
Odd scenario here and perhaps you can offer some insight. I’ve got a relatively new Mac Pro, 16 gigs ram, lots of drive space, Kona 3 with IO, A500 digibeta, and a blackburst generator going into everything. We are running all the latest AJA software/firmware and Leopard is 10.5.6. My Digibeta out ref is set to “Ref” and my Kona Control panel is also setup to Ref in. Tapes lay back correctly and I haven’t run into any red channel errors and we’ve done lots of laybacks. So, I believe that this is NOT a ref issue.
Here’s the problem. I have mac audio set to output via the Kona (output is about 3/4 to full). I’ll listen to itunes while working and all is well. Until….once a day roughly, I’ll be listening to music and the audio will gradually become distorted until the point of being completely inaudible over the course of a few minutes. I’ll shut down some programs and it will eventually come back. This affects everything coming out of the Kona card.
Does this appear to be a faulty kona 3 card issue? I tried changing the ref settings in the aja control panel in the middle of the last distortion field I entered, but to no avail.
Thanks for your advice!

I’ve run into this anomaly with iTunes too, if I switch between FCP and iTunes.
If I am doing something tedious in FCP that doesn’t require audio monitoring, and I want to listen to music, I just use my ipod now.

Crazy thing was, today I just had ichat/mail/safari/itunes open when it happened. There wasn’t any hardcore work going on other than I had just booted up about 30 minutes prior.
