I am running Vista64 but I can simulate dropouts by reducing the asio buffer size to around 96 (I have it set a 256 in the YSFW driver control panel), maybe buffer size is too low? Or an IRQ conflict (or video card driver issue re. screen flicker?)

Hi Brian, Thanks for the helpful advice. I have tried many things to solve this - changed graphics card, bought and installed another firewire card, changed firewire cable and this morning tried the new card in my sons vista computer none of which has made much difference. The audio dropouts are so bad that changing the buffer size does not help. Yamaha support has advised me to get the unit changed so it is boxed up ready for pickup tomorrow (today now its late!). The sp3 issue is interesting as I thougth it was confined to firewire 800? Running the N12 on the vista computer should rule that out I would have thought? I don't fancy de-boxing the N12 now its ready to send. I hope in one way that it is faulty and the replacement solves the problem, I will have egg on my face otherwise although I think I have tried extremely hard to get it working. I will let you know how things work out. Bob
