I have 1st generation Duet, macbook pro OS 10.6.8. Duet now does not record. Occasionally on playback it just makes a lot of crackling noise. Not sure if it just died.
Yes, I have a first gen Duet, and my laptop is one of the first macbook pro generations and I don't have 10.6.8, only 10.5.8. The symptoms are different as well. I can't even get to the point of recording. The moment I plug in the firewire, the inputs peak like wild.
What's odd is it doesn't do this with my MacMini running 10.6.8. Bizarre, I'm thinking I'll have to call Apogee direct.
I guess by rationale, one might suggest installing that on my laptop. I think I might call Apogee first before doing so just to get some kind of explanation. I've had issues with Snow Leopard upon install and re-installing all my software sounds like quite an undertaking if I have a bad install.
